Server not responding - Many unable to join Servers

Similar problem- notice how in the log file there's a line about the server responding AFTER the connection has 'failed.' This could have something to do with the loading into single player- the data about the default world (star system) gets loaded and the loading in gets initialized, but then the actual data- voxels, grids, etc. fail.

Some Server side logs since I was asked for it https://drive.google.com/drive/folders/19cLmIF10rCcKn0ymRmHl_XOEPLdweIx_?usp=sharing are too large for the site apparently

I am also having this issue on every single server as well as others. I can join servers from other games just fine

It’s really annoying when it fires up into offline mode game. Literally nobody wants this outcome.

For me Connecting works fine, until you come across a server with mods.

When it's up to mods, it's downloading some (like 1-2mins max) and then aborting the connection, and i will get this message too.

Atleast for servers with mods downloading all the mods manually before joing the server has worked for me so far

I have had this with modded servers and tried subscribing to the mods the server uses before hand. That didn't work for me. I tried unsubscribing from all other mods and only keeping those specific mods, that didn't change anything either. I've ended up in a single player world after trying to connect also. I haven't been able to connect to any modded servers since the update.

I have this same issue as well. Though when I did disable my firewall for a moment it started to join the game but this time said the host has left the server and after reconnecting again it displayed the same message of "Server not responding."

I'm having the same issue, but it's as 69 people so I'm not gonna press the button

Same issue here, No fix so far. Keen seems unwilling to patch it and only wants to focus on vanilla.

I am wondering if it's not a Steam Server issue.

Right now I can't connect to my server and when I check steam status, it seems EU west servers are offline.

Really need some fix. Players just can't download mods before they kicked. Maybe it's possible to give us some tool for setup timeout on DS?

Is this not being investigated anymore?

I am also getting this error on a dedicated server I host. I will see another player on my server, and I will not be able to connect to the server. It may take me about 6 to 8 tries attempting to connect to the server for it to let me in, or a server restart.

Bug is still here, there has been no fix as of yet.

This problem still exists and its making this game extremely hard to play and manage. Any dev response on the issue would be appreciated

Someone from Discord had told me that if you have a 200 plus ping then the server you are connecting to immediately kicks you due to your large download time whether it is modded or unmodded. Hope this helps.

This happens frequently on modded servers. It's as if the interface timeout is shorter than the mod download period. I run a server with ~50 or so mods but have noticed this issue occurring when there is a single large mod to be downloaded. This makes it impossible for new players to join my server as they simply move on from one server to the next without knowing what the problem is and the only way to let them know is add them as a friend on Steam and inform them to download the mods in advance.

So want to add my 2 cents here.

The last update to public caused some sort of issue that is just like this issue.

I went to join Keen official servers, so unmodded, vanilla DS.... and repeatedly I was unable to connect.

I restarted my game and was able to connect after 1-3 attempts.

If I reconnected, it gave me 'server is not responding' messages consistently.

Not sure what was changed recently but this didn't happen until the latest public update.

I've had the same BUG for months.It's frustrating because new players can't join and don't reconnect again...

Still not fixed? -.-

Strange, but i seems have problem only when i try to join server with mods (in process downloading mods appear).

I am suprised by this. I play 5k+ hours and now this problem. Please Keen help us..

so this is not a mod issue this is not a person made map issue. I have reset the server fresh no mod files on the server wipe the server clean and a fresh install changed nothing in the configs just started the server up and still the same thing. some feed back from you keen would be nice. are you looking into this? have you found anything? do you ever care? im getting to the point where im getting ready to file something with steam.

Hi guys,

thanks for your messages.

We are trying to reproduce this issue.

After update: I still had an issue joining a server for the first time, although instead of failing and then firing up the world in single player, I got stuck at the respawn screen with infinite loading wheel icon.

After reconnect, I went straight into game already spawned, no respawn screen.

Similar cause, different effect, still not quite right.

yeah having this same connection issues as well also 7 months thats a long time for a reply with no promises anyways ive ran into a little problem of my own i cant even see any of the servers each time i load up now first time its happned to me stil owrking to get it fixed if its on my side but something tells me its not on my side.....

and another thing bc of this issue it has ran alot of popular servers into the ground

Hi Everyone,

In order to address these types of issues, we need moddless save files or the IP address of the active server.

Additionally, please keep in mind that if you're utilizing Torch, specific mods or if you're having connectivity issues, we cannot guarantee optimal performance.

Please send all of the necessary information (save files without mods, IP address of the active server) to our support site:

https://support.keenswh.com/spaceengineers/general and we'll be happy to investigate each specific case ASAP.

Lastly, we apologize for the late reply, but we had to prioritize addressing other issues before we began looking into these problems that you have reported to us.

Thank you and we appreciate your patience.

The Space Engineers QA Team

P.S.

If you're unable to attach the moddless save file via our support side tickets, please upload the file in-question to Google Drive and send us the link.

A number of other bug/feedback submissions on this site fall right under this issue.

Our community server is going through this same problem. We haven't found a solution. I have done everything from a clean server install, to reducing mod count. Everything aside from a new world file.

Watching the logs I see failed connection attempts almost constantly. Yet players CAN connect and play....

No one solution has worked for everyone. When I couldn't connect, I resolved it by doing a game validation. When it happened again, I was able to resolve it by either spamming 'connect to server' or restarting the game and steam. Other players report doing a variation of things, and eventually getting in. Some players are still trying, who knows how many haven't/won't bother.

In the topic of modded servers, it's likely because the game automatically times out when trying to connect to a server and downloading workshop mods. The timer runs independant of any actual connection to the server, it only starts when you attempt to connect, and ends when it runs out, instead of resetting when getting a response from the server.

I was just gifted this game from my friend and we can't really play together because of this connection issue.

What I was able to learn so far is that the server is flooding too much data at once, which also causes some older routers to detect it as DOS attempt and cuts the whole network connection for a bit. Optimizing this data transfer might solve it for everyone.

Noone on the server i was playing could connect to server then admin said he can join without problem some of us needed to validate SE files some of us needed to reinstall thier workshop mods some entire games and some entire steam and i'm one of many that not even validating or reinstalling worked because of this but many of players can't play,

I posted a thread on the reddit that contains a client-side plugin for an immediate fix, as well as source code and a diff that Keen can apply directly to the source.

https://www.reddit.com/r/spaceengineers/comments/f7ul3s/fix_for_server_is_not_responding_error/

So, I took rexxar's fix (thanks!) and I investigated it more. There's an even simpler fix I'm going to submit:

        public static bool IsScreenOnTop(MyGuiScreenBase screen)
        {
            if (m_screensToAdd.Count > 0 || m_screens.Count == 0)
                return false;

            return m_screens[m_screens.Count - 1] == screen;
        }

That's all of it. It replaces the old method that was there. The old method was doing something very odd to detect if the specific window was on top.

The trouble is, the mod downloading message is a MessageBox, and for some reason, it wasn't being checked. Since it was the topmost window, that old method returned true when it should have returned false.

I'll be submitting this fix directly to them. We'll see if they accept it.

EDIT: I have submitted it.

Pathetic!

How would you do this? Im new to this

Hello, Engineers!

Are you still experiencing this issue in the newest version 194.211? We made some adjustments that should fix this issue, at least some of the cases.

Thank you for all your information.

1.197.073 still same issue "server host left"

I recently Installed Space Engineers on my new computer, on a brand new hard drive. I have no mods currently installed. I can play single player on my computer. The problem I am having is I am unable to join any server at all. Not the official servers or hosted servers. My friend setup a server through Nitrado, and all of my friends that have the game are capable of joining the server and playing, but I can not join it or any other server. It also appears that when I do try to join my friends server that it crashes the server and causes it to restart. We have tried to connect for several days now and it keeps doing the same thing. I get a message saying that "The server host hast left the game" and then it attempts to reconnect but it never does. I used to be able to play the game just fine, so what has changed about the game that is preventing me from playing on any server? I have all the DLC. I have uninstalled the game several times and verified that all files were removed from my computer, and reinstalled the game. I have verified the files several times. No matter what I do I always get the same result as stated above. PLEASE HELP IF YOU CAN!

Also, have soma problem. But sometimes I join the server but it's in the offline mode.

This has been a problem for me for 3-4 updates now. I can only play solo games. I have tried to host a dedicated server on a server I own. I have purchased server space from a 3rd party. I have even tried connecting to an official server. None of them work. I'm starting to think they either can't fix it or don't care. This problem has been around for years and seems to be expanding on who it is affecting. I really hope someone can figure this out.

I am experiencing this issue aswell. I was able to join a specific server one day, now im only getting server not responding issues. Ive checked with many other of the players who play said server, none of which are having the same issue.

When my server stops responding, I simply connect the remote client. After that it immediately appears in the fav list again...

Keen Support, what additional information are you looking for EXACTLY to move this ticket along? Gwindalmir proposed a code fix already for this game bug. do you need client logs? if so, which ones do you need? server logs show ZERO connection attempts by the affected player.

I bought a new computer and now have this issue I get the "Server not responding" or a "Server Host left" Message shortly after trying to connect, I never had this problem on the old computer. I have tried starting a new game hosting on my computer and no one can join. Also tried to join a game hosted on my sons computer i get server host left and his game crashes. He is able to join servers normally.

My old laptop still works just fine. Oddly it doesn't meet system requirements for the game, but can run not only solo games but also connect to any server I want. My new laptop which not only meets but exceeds system recommendations can't connect to any servers even ones that I host on a server within my network. I have tried connecting to the "Recommended" servers and it crashes them also. I don't know what log files you are wanting. Do you want client side logs, server side logs, computer specs, you tell me what you want and I will find a way to get it to you. I just want to be able to play this game with my friends. I can switch back to my old crap laptop that for some reason can run multiplayer just fine, but I would rather play on my new laptop that looks amazing. Please figure this out or at least show some signs of trying to fix it.

I have the same problem. Constantly "Server not responding" or "Server Host left". If I sometimes finally connect, after a few minutes in game I have a download 0 and a disconnection.

I couldn't join on any server with mods and with out mods

I was just watching what was happening while trying to connect my server. My server is sitting about 20 feet from me. Whle not trying to connect I have a ping of 1-2. As soon as I try to connect to my server my ping hits 130+. There is obviously something causing huge latency spikes. I am not sure what would be causing that, but I hope this helps. I'm not seeing anything from Keen on here anymore so not sure they are even watching this thread.

Update on my issue.

I have 3, computers sitting side by side all; plugged into the same router, and each one with its individual steam account. Computer 1 and 2 log in to space engineers just fine and can join servers normally including games hosted on each other but not on computer 3. Computer 3 can play solo games just fine; but not login to a multiplayer game on a server, or hosted locally on computer 1 or 2.

Because computer 3 can play solo, I bought all the DLC's for it last night and decided to try to log in to the server. Holy Crap it logged in and played perfectly I was so happy until the server gave a reset warning we all logged off and waited 5 minutes. When we logged back on computer 3 started with the warnings again (server not responding) and now won't play remote games again.

I am bewildered by this what is going on and how do i fix this.

Hi,

My friends have been trying to join my dedicated server for a long time. Dedicated server is hosted from my computer with no mods. It's a basic solar system. Settings are standard with options turned on with friends who can join.

I was using cell service as the internet before but now I'm back to using fiber net. They still can't join. We tried with my firewall disabled. Didn't work. All of us checked the steam side of things in terms of any corruptions ect. Nothing changed.

Hey everyday,

After a year or more of trying to sort this crap out. Port forwarding, uninstalling, different machines etc. nothing worked. I came across a reddit post regarding ISP's using something called CGNAT carrier grade network address translation. CGNAT prevents any port forwarding and so whatever I did was useless. I spoke to my ISP and they did in fact confirm that CGNAT was in use and that yes it did prevent clients from port forwarding and they offered to opt me out of using CGNAT.

Once they did, I was able to properly port forward the ports and they were actually opening. Installed Space Engineers and BAM joined a server straight away no fuckin issues whatsoever. Everyone having issues with joining, I suggest contacting your ISP.

Find this thread here, which has a DLL that actually fixed this issue, if anyone else runs into this issue!

https://support.keenswh.com/spaceengineers/pc/topic/multiplayer-server-dumps-you-into-single-player-when-trying-to-join

I have tried this .dll and it doesn't fix my problem. I'm not being loaded into a single player game it is crashing the server completely. My internet speed is well about the required. I ping around 80Mbps. Even after the most recent game update it is still crashing the server.

I had same issue when took model and voxel details to max; lowering those allowed me to join same servers.

Hello, Engineers,

as this thread is quite old now, with last comments from you as well, can I please ask you whether any of you are still experiencing this issue?

If yes, can you write to us more information, whether and how the issue changed/is observable now? Or was it fixed in a meantime?

Thank you in advance for any update.

Kind Regards

this is a demonstration of what I mentioned, its on my YT channel

Is there any update on this issue? Have we even figured out if everyone is having the same issue? I'm really missing playing this game.

Hello, Engineers!

This thread is quite old now, if we can ask, is this issue still happening?

If yes, can any of you kindly provide us with some more information, like, if the game is crashing or the whole server is? What does the crash look like, does it take you back to the Main Menu or crash to the desktop?

Does the issue persist even after following the advice from other players in this thread? Is this issue mostly being experienced when having high ping, joining multiplayer servers while having active VPN/Antivirus/Firewalls, and slow internet connection speed?

We also recommend lowering the Graphic Settings to a minimum and trying to join multiple servers again.

If the issue persists, kindly send us the log files.
