Multiplayer Server dumps you into Single Player when trying to join

SeliG shared this bug 4 years ago
Solved

95% of the time when i try and join the Draconis Cluster I get the screen "waiting for the server to respond" then a the normal loading screen only to find that the game has loaded me into a Single Player game. Its happened before but seemed to be much worse after the Frostbite update.

84 I have the same bug

I was coming here to submit this to the forum, but since you already did, let me add some of the data I've collected in my testing:

During a client connect request -- this is what we see in their SpaceEngineers_{DATE}.log:

If anyone at Keen needs to see the server and client logs from the specific event, direct message me. I have multiple long time players on my server with this issue, and I can provide all the logs for client and server side during the occurrence of this bug for 2 of them off hand, and more if needed.

Please fix it soon. We have around 20+ players on our server, having this issue. But not active on your forum for voting.

Brian Bartsch ● 4 years ago

Send them here and convince them to vote on it.

No vote == no proof they actually exist


The only way to get this higher up is more votes.

Got 5 players from our server to vote.

Others don't believe Keen will fix it anyhow, and uninstalled the game.

I looked over the logs you uploaded and it looks like mine. World requested -- and then about 45-60 seconds later, World requested - failed, server changed.

I've noticed more overseas players tend to have this issue, not sure if it's related or not.

Mark McCorkle ● 4 years ago

As I believe it is a client timeout -- long distance players (like being over an ocean) more than likely makes the problem worse.

It's possible that one log was a bunk and missed the connection attempt - we had multiples from that player

Mark McCorkle ● 4 years ago

To follow up on some testing I did over the weekend.


I stood up a second server instance on port 27017 of the same physical machine. Same Mods, same settings. The only difference is that the 27017 server had no existing grids, and no existing voxels to download and parse.


For all my players that have had this connection problem, I asked them to attempt to connect to the secondary server. They were all able to connect and reconnect to the 27017 server with no observed issues. They then attempted to connect to the main server (27016) and had the same connection issues -- either a server timeout, or this edge case where they get dropped into an offline world.

We did additional testing as well, and having players essentially wipe everything about their mod list and rebuild it has helped them, using steps below 

Close Space Engineers; Use the "Unsubscribe from all" option on the modlist collection linked above ; Close Steam; then delete the all contents of the "…Steam\steamapps\workshop\content\244850\" folder and the "appworkshop_244850.acf" file mentioned above; then relaunch Steam and monitor the Downloads screen and wait for all "Space Engineers - Workshop Content"  to finish downloading.

Over this past weekend, I cloned the FULL server that has been having the problem:

The I did the following cleanup:


* removed all the voxels that were > 1500 m from a grid

* I removed all the un-used identities, factions, and relationships from the file (using some admin tools from Torch).


After that, I had players test again -- and they were able to connect much more reliably to this new "cleaned up" server. I did have one report that they couldn't connect, but that might be an outlier.


Just following up -- I believe the problem was that my sandbox file sizes + voxel files were the two things that, when combined, were timing my players out, and dropping them into this single player (offline) mode.

photo

Brian Bartsch ● 4 years ago

We do voxel cleanups weekly (remove all roid vx2's; reset all planet voxels) and still have players have issues directly following that.

We have Sandbox.sbc files ranging from 30-90MB across 6 instances. Reports of getting dropped to single player occur on all 6; most often on the two instances right around 63MB for a Sandbox - but the two at 30MB still see the issues with players too - and those same players can go join one of the other servers with a 90MB sandbox fine, and we're generally looking at <5MB (up to a max of 12-13MB usually ) of vx2 file sizes on any of these instances because of the frequency of cleanup we do for it.


Unfortunately we can't remove unused identities/factions/relationships in our environment to shrink the main Sandbox either but I'm not positive it would help

This is the kind of bug that makes me realize that Keen did now know what they were doing when they coded this game...

Brian Bartsch ● 4 years ago

For anyone fighting this, here's a fix we got from Rexxar (client side plugin).


We keep our writeup and link here -- https://wiki.sigmadraconis.games/doku.php?id=introduction:connection_issues#known_connection_bugs


This is an *updated version* of the one he posted on Reddit a while ago for a different join issue, so don't confuse the two. This will report "Rexxars Code v2.1" when loading the world and have v2.1 in the client logs.


We've had >100 players successfully fixed with this dll. 


Download the plugin dll to SE_install_dir/Bin64/Plugins (the default is C:\Program Files (x86)\Steam\steamapps\common\SpaceEngineers\Bin64\Plugins). Create the Plugins directory if you don't already have it.
Plugin download link: http://sigmadraconis.games/TimeoutFixPlugin.dll
Right-click TimeoutFixPlugin.dll, select properties, then check 'unblock'
Set SE to use the plugin by opening Steam, right click on Space Engineers, select properties, click "Set Launch Options" and add (without the quotes) "-plugin Plugins/TimeoutFixPlugin.dll"
That's it; try joining. You should no longer drop to single player. You should either join successfully, or receive "Server not responding" , or be returned to the main menu of the game.
If your game crashes on launch it is because you did one of the following. A copy of your SpaceEngineer_xxxxx_xxxx.log file from '%appdata%/SpaceEngineers' can explain which the issue is

Did not unblock the dll
Did not properly name the DLL or Plugins folder (it is case sensitive)
Created the Plugins folder in the wrong location

Brian Bartsch ● 4 years ago

Update -- this fix no longer works was of v195 (sparks of the future update), it crashes game on Launch, so players are dropping to sp again.

Brian Bartsch ● 4 years ago

Sat down with some people, there is now a fixed version at the URL in the original comment here (http://sigmadraconis.games/TimeoutFixPlugin.dll). Prints as v2.2 in logs and on screen (previous was v2.1).

It's been months and I can't even troubleshoot other server issues because I can't join the server thanks to this bug :)

Hello Brian!

Is this happening with a particular server or, is it any you join? I see you had a few fixes over time but these are no longer working. How frequently is this happening for you?

Kind Regards

Brian Bartsch ● 3 years ago

The most recent file I attached (timeoutfix.dll) works currently still to fix it so I don't see it anymore. It mainly occurs on servers with large worlds (<100MB Sandbox.sbc size), but is not unique to any certain server. If I use a program to artificially limit my internet to a slow enough speed it can occur on the Keen official vanilla servers or even to a vanilla DS running in my same home.

Still an issue for many players reporting to us, unless one uses the timeoutfix.dll i most recently provided

Still reproducable / an issue in version 1.198.027

Brian Bartsch ● 3 years ago

Still reproduceable as of last week. Easiest way to reproduce is use very poor internet. We have a player who is on very slow DSL and without the fix listed above they are constantly dropped to a single player copy of the world.

Laura K ● 3 years ago

Hello, Brian!

What speeds are they getting? On the system requirements for multiplayer we recommend 5Mbit/s or more

Kind Regards

Brian Bartsch ● 3 years ago

From their speedtests, 6Mbit down on average and like 0.3Mbit up

Brian Bartsch ● 3 years ago

I want to mention too - failing to connect because your internet is too slow for the game is one thing, and there's nothing needing to *really* be done about that (though it'd be nice if the connection timeout was either longer or dynamic based on activity of connection); the core problem is that people end up in a local copy of the world that confuses them (has their gps and some other data for that player, but not factions or grids and stuff like that). It leads them to think they are on the server when in reality they failed to join

Pyxaron Dragon ● 2 years ago

Just to say, i've had this one happen to me too, it's nice because it gave me a sandbox copy of the server's world to do creative builds in, but it's a pretty strange bug.

LeakingAmps ● 2 years ago

This is still occurring. Playing with a friend, and we've been playing for a few weeks, no problem. Now I try and connect, and I'm just stuck waiting for server to respond, and then "Server is not responding", while the server says I've joined. A few times it dumps me into SP, but usually back to the main menu.


Attempted to fix it by uninstalling all my mods, did not help. Will try the DLL tomorrow, if the host is up for it.


Logs show the same errors as above - connecting fine, when it says "World requested - failed, server changed", and then disconnects.

This still occurs, although the most recent update helped enough that failure to connect at all now only occurs under significantly adverse network conditions (>10% packet loss, <1mbps), instead of occurring even under stable conditions (<0.1% packet loss, >100mbps) and I've not been dumped into a singleplayer since the update. I'd say it's probably safe to consider it fixed.


Edit: In addition, the patch posted on the forums for this bug ages ago does not help anymore if you are under such network conditions. There's only so much that programming can do to compensate for a bad network.

This is still a problem. We still get reports. A VPN taking a long route around to the server; or say....connecting from africa->canada based server; players drop to a single player copy of the world.

I am having this issue and can't play on any multiplayer server. I don't know what to do. I can't join multiplayer servers because when I do it loads in a sudo spectator where I have no GUI but can fly around in spectator view. It also saves the Storage folders from the save but not the with the planet or Sandbox files in my offline saves folder. Does anyone know of a fix for this? I already reinstalled my computer completely. Is anyone at keen still working on this issue?

This glitch makes the game literally unplayable on multiplayer. I have had this issue for several days already and tried many possible fixes including Raxxar's local plugin. with no luck.
