Server not responding - Many unable to join Servers

Kuroshi shared this bug 10 months ago
Investigating

Since the release, many people have problems connecting to servers. They will get a "Server not responding" or a "Server Host left" Message shortly after trying to connect. They then have to keep trying until they eventually get in.

This is a huge bother for many players and appears to get worse on bigger worlds.Additionally, sometimes players load into a single player world of the server which also saves locally.

Some logs are attached and I will tell people to post their logs when it happend here

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

Let's be honest, John. If this game breaking bug has been around for 3 months I highly doubt they'll be touching it any time soon. The only sign of hope we ever seen was when they switched it to "investigating" but that's honestly about it.

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.

Yeah I just put a comment on the description page telling them about my collection, As long as they subscribe to it and download the mods it'll work. I have no clue why its so hard to fix something that's so simple. You could join modded servers before this major overhaul on survival.

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? -.-

Maybe the fix will only come with the next major update.

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

and we get "host has left the server" this started just yesterday out of the blue. one guy DCed and came back to this while I was still playing with no issues. I then DCed my self to see if it was just him.....and you know what I now have the same issue. im shelling out money for a server that no one can connect to now and you've got my money for the game and the DLC how about fix this! problem is more than 6 months old ive seen reports as far back as 2014 of this issue. think that's plenty of time. and no im not happy right now.

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 6 months of this being posted? Sounds like a new record.

I have a server hosted on GTX and last week this started happening to me. Being the Admin its a big difficult that I can not get connected most of the time. Happy to help any way I can.

This is the error from my client side log that seems to be where things go wrong. World requested - failed, server changed

@ 0x00015 - The record has to be the "grid anchored to space" bug which persisted forever and was never able to be reliably reproduced despite happening constantly.

OK, so for my server I was using Torch and Essentials. Essentials has a setting to preload that planet data. By turning this setting off I was able to mitigate the problem for all of my users. The logfile shows the volume of data sent to the client dropping from about 26 meg to less than 1 meg. My guess is the data being sent is larger than the clients internet connection speed can transmit before the hard coded timeout occurs. From the Git repository of the game code from a few years ago that hard coded timeout appears to be 40 seconds. I suspect in very large environments with more bandwidth constraints you may see this issue show up even without torch. I began to suspect the size of data being sent because of the profile of users that had it happen and the type inet/speed they had with other things in the household. I even noticed it worse when I was streaming content and trying to connect at the same time. I wanted to share my experience so that others can explore more from where I left off.

No thanks, If it's a bug only reproduced in experimental they will most likely avoid it or just say there was no way to reproduce it. Why do you think there is an experimental mode? ;)

This does sound like it's related to syncing on_connect. you can always feel the lagspike when a player connects on official servers when you have more then 6 players connected. If said player has a bad connection they will most likely timeout trying to sync as they connect to the server. If the sync size is too big they get disconnected before the sync is completed due to a timeout on the connection end. We do know it says "connected" way before a player can even interface. This should be streamlined on the side and have a loading indicator instead of just letting them hang in the loading window with nothing to indicate whether they did succesfully connect or not.

We had multiple players in our official faction that had bad connections that has a very high disconnect rate when attempting to connect with 6+ players in game. peak hours are their worst hours they say.

If the syncing was queued even with an indicator or delay pr. active player it would be easier and less heavy on everyone. plus you'd allow the player to be able to chat while observing their current synced status.

I have I 1gig fiber line bud its not my internet. 30 ping to the server

i said it had a very high impact the low connections, syncing is server controlled. hence the reference to the "lagspike" for everyone when a player is connecting.

I am on a high end computer with same internet specs and even have the same behavior on a LAN connected server when external players join in. it is not optimal nor optimized at all and does affect players both connected and connecting ones.

Maybe rather than try and reproduce it, you get with server owners who are currently dealing with it?

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.

Example server IP: 74.109.255.173:27016

The server is running mods, but as you are likely aware, mods do not have any possibility of influencing the connection. Additionally, torch plays no role in this either since the client is the problem

Making a save file for this is nearly impossible due to the bug being connected to the connection timeout among other things. Mostly the initial cause is inoptimal connections which the game can not handle, even though they were previously completely fine and should be well good enough for any kind of connection. I recommend testing with a speed limit of 50mbits download or lower.

Here is some log linked for you, you can see the clients time out https://drive.google.com/file/d/1mRhKcBAJubuANoArL5nZH-uOCHztW0jJ/view?usp=sharing

Additionally, if you want the easiest reproduction for this, try joining a server whose mods you have not loaded. you will get the "Server not responding" message while downloading the servers mods, despite there obviously being an established connection in which the server responded. the same happens for very large vanilla worlds

Sounds like multiple issues. I get the first issue, but the workaround of waiting for steam to download the mods has been working. Albeit, it'll try to load a local copy of the server's game from that first attempt, which I don't find very useful. But IMO it all works in the end (sort of). The second sounds more serious if you ask me, but I don't know if Keen can do too much about it. Kudos Keen if you can.

Edit: Unless your focus is about the false feedback from the game, which I also find to be very problematic, but more fixable.

Sound like they aren't even remotely close to understanding what is going on, if they are still testing this issue on moddless servers.


That's a real disappointment.


I'd be happy to provide access to my logs, and server files in general if it would help.

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.
