Game disconnects a few minutes after joining a multiplayer server

Wiktord1

Official Terrarian
EDIT: The issue seems to have fixed itself, so the thread can be ignored now. Thanks a lot for your help, still :)

Me and a few friends were playing on a multiplayer server through Steam. The game worked fine for around a week, maybe except for a bit of lag. But one day, i joined the server, played for a few minutes, and then terraria decided "nah", disconnected me from the server for a reason i dont know and left me confused with a "Lost connection" message. I tried to rejoin, but the same thing happened - I played normally for a few minutes, then game lagged out and disconnected from the server shortly after.

I tried many things, for example:
- Restarting the server
- Redownloading the game
Even after i deleted all my game files and redownloaded Terraria again the problem doesn't seem to go away.

I've seen a few posts about people experiencing the same problem, but none i've found in a working solution. This really annoys me because it kinda disables me from playing multiplayer.

Obtaining Logs via Terraria (New)
There is now a new way to obtain logs of Terraria and try to identify the issue at hand. This little method requires a bit more work, however, we provide you with some instructions on step by step on how to get this working. Please make sure that you check which version of Terraria you have before doing this. Note that the Steam version is slightly easier than the other one.
Log Location: C:\Users\<User>\Documents\My Games\Terraria\Logs

Steam Version
There is no special requirement with steam as it is one simple platform.
  1. Open Steam Library.
  2. Right-Click Terraria on the Library and select Properties.
  3. Select General Tab, if not already selected.
  4. Click Set Launch Options.
  5. In the text box insert -logerrors -logfile

GOG Version
There are different procedures for the operating system you are using, we will try to get them for all.

  1. Create a shortcut of Terraria Executable.
  2. Right-Click the Shortcut and select Properties.
  3. In Target Box, add at the end the parameters -logerrors -logfile
Troubleshooting Your Problem with TerrariaServer.exe
In order to figure out what your problem is with the game, we require that you run the Terraria Server Client (TerrariaServer.exe). This will display any errors or successes on launch. Should there be any errors from the program itself, use the command prompt and copy the error to display it here.
  1. Right click within the Command Prompt.
  2. In the drop-down menu, select Mark.
  3. Once you made a selection, Right Click or Press Enter to copy.
  4. Paste your results in your thread.
If you have trouble with the above instructions, your system might be showing "Not Responding" or your System may need to be rebooted to start clean.

Deleting the JSON files to clear Terraria Settings
Before proceeding any further, please delete the config.json file located in your Terraria Folder under My Documents/My Games. Then start Terraria again, this may fix some unexplained issues, but we wish to make sure you are running a nice and clean installation:
  1. Locate My Documents Folder.
  2. Open My Games Folder.
  3. Open Terraria Folder.
  4. Delete Config.json file from this location.
    • You can also delete the Favorites/Profile files as well, just in case.

Frequently Asked Questions

Q: My world has corrupted somehow and will not load properly, what can I do?
A: You may have corrupted the world by using modded clients, computer shutdown before the world could complete the save, or system failure within Terraria that caused the problem. You can try attempting to load your world using TEdit (Download).

Q: My game is not launching, or I get errors regarding XNA/.NET Framework!
A: You can attempt to make sure you have all Game Dependencies first, then try attempting this solution:

If you don't feel like sifting through all that, it's basically to do with the framework permissions.

This is how you change the right to use Framework/XNA:
  1. Right-Click the specific directory (Listed Below).
  2. Select Properties.
  3. Select the Security Tab
  4. Click on Advanced Option
  5. Select the Owner Tab
  6. Click on the bottom button to Edit.
  7. On this window select the Administrator in the row and make sure to select the Checkboxes below.
  8. Hit Apply and close all the windows.
  9. Try running the game again.
Do the above for all of the following FOLDERS:

C:\Windows\Microsoft.NET\assembly\GAC_32:
Microsoft.Xna.Framework\v4.0_4.0.0.0__842cf8be1de50553
Microsoft.Xna.Framework.Game\v4.0_4.0.0.0__842cf8be1de50553
Microsoft.Xna.Framework.Graphics\v4.0_4.0.0.0__842cf8be1de50553
Microsoft.Xna.Framework.Xact\v4.0_4.0.0.0__842cf8be1de50553

C:\Windows\Microsoft.NET\assembly\GAC_MSIL:
Microsoft.Xna.Framework.Avatar\v4.0_4.0.0.0__842cf8be1de50553
Microsoft.Xna.Framework.GamerServices\v4.0_4.0.0.0__842cf8be1de50553
Microsoft.Xna.Framework.Input.Touch\v4.0_4.0.0.0__842cf8be1de50553

Microsoft.Xna.Framework.Video\v4.0_4.0.0.0__842cf8be1de50553

Q: Steam has reported that one (1) file has failed verification and was downloaded?
A: This file is known as the serverconfig.txt file. Originally this file shouldn't be packed with the game as Terraria should create this file automatically on launch if it is missing or out of date. Due to it being changed and updated by server owners, the file will constantly fail the verification process. This has no effect on playing the game, and can be ignored.

Q: I am experiencing low frame rate for Terraria, but the machine passes as recommended?
A: If you are using nVidia Control Panel, you can select Terraria.exe process and change the specifications on how your graphic card handles the game. Follow these instructions:
  1. Open nVidia Control Panel.
  2. Select Manage 3D Settings.
  3. Choose Program Settings Tab.
  4. Select Terraria as current program.
  5. Turn Triple buffering and Vertical sync to On.
  6. Run Terraria and turn Frame Skip to Off.
  7. The application should be running better than your current setup.

Alternate Solution (The Aero Mode Bug)
  1. Goto your Desktop.
  2. Right Click and Select Personalize.
  3. Enable Aero Mode by selecting an Aero Background Option.
  4. You can also go Fullscreen Mode while Disabled Aero Mode.
Q: Experiencing an XAudio Driver Issue?
A: Check this out about the error: http://forums.terraria.org/index.ph...out-due-to-xaudio2_6-dll-on-windows-10.32894/

Q: Missing XInput Driver for the game?
A: You can download Microsoft DirectX Web Installer and fix this issue properly. We do not recommend searching for the driver (DLL) manually. Download it here.

Q: Where can I find my world and player files?
A: You can find your world and character files based on your system here:
  • Windows: <home folder>\Documents\My Games\Terraria\Players
  • Mac: ~/Library/Application Support/Terraria/Players
  • Linux: ~/.local/share/Terraria/Players
However, if you're using Steam Cloud Sync, the files will be in a different location.
  • <Steam directory>/userdata/<Steam3 ID>/105600/remote/players
Q: Users with Windows 10 and Terraria Crashing (The Encryption Fix)
A: Apparently Terraria uses a specific encryption method, some OS types do not allow this like Windows 10. This can be fixed!


Terraria uses the RijndaelManaged class for player encryption, which isn't FIPS (Federal Information Processing Standard) compliant. There's a flag in the registry that tells Windows whether it should allow non-compliant encryption methods to be used. The registry key is:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa

If the value fipsalgorithmpolicy is present and set to 1, non-compliant algorithms will be blocked and will throw exceptions if you try to use them (like you got). Setting it to 0 should fix the error.

You might also want to check: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\FipsAlgorithmPolicy

In case you don't understand the above text, I'll explain it by step:
  • Press the Windows Key (Button) and search for REGEDIT.
  • Browse to the location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
  • Locate the fipsalgorithmpolicy key and edit it by set its value to 0, or find the map with that name and disable it.
If done, I think the error wouldn't appear anymore.

Q: Framerate dips down to 20 FPS or lower, and then comes back?
A: This sounds like an issue with the CPU Affinity, you can set your affinity and see if the issue resolves.

  • Start Terraria.exe
  • Start Task Manager from Windows Start Menu or CTRL+ALT+DEL.
  • Locate the Process Terraria.exe.
  • Right-Click and choose Set Affinity...
  • Remove CPU 0 from the selection.
  • Terraria.exe should not be causing any issues now.

Q: How can I force Terraria to dump log files?
A: You can force Terraria to dump log files in the Documents Folder where all other data is stored for the game. Simple add "-logerrors -logfile" to the end of the shortcut of Terraria, this may depend on your operating system you are using. If you are using steam version, simply place these parameters in Terraria via the Properties and select Set Launch Options.

I am having the same problem, after a few seconds I am disconnected from my friends game. I know its not my firewall, my system requirements, or my internet connection. I tried downloading .net but it already said it was installed. I am really confused what to do now.
