Fast answer
Start with the official Steam store and Steam Community pages. Many connection errors come from network tools, outdated requirements, or incorrect launch configurations. Before changing system files or trusting third-party fixes, check the current official pages because game updates can fix or change known issues quickly.
| Symptom | Common cause area | Safe first check |
|---|---|---|
| Game does not connect | Network tools, firewall, or server region | Compare with friends on the same network |
| Not logged in error | Steam login or network interception | Restart Steam and check connection tools |
| Low FPS | Graphics settings or driver version | Compare minimum vs actual specs on Steam |
| Crash or freeze | Driver conflict or corrupted install | Verify game files through Steam |
| Voice chat not working | Audio device or in-game setting | Check Windows or Steam voice settings |
| Painting tool not responding | Key binding or eyedropper issue | Test painting controls in a private room |
Game not connecting
When the game fails to connect, the problem is often a network tool or firewall blocking the game's connection. If you use network tools such as VPN, proxy, or traffic redirectors, disable them temporarily to see whether the game connects. Check the Steam store page for current server notes because online infrastructure can change. If your friends connect but you cannot, compare network environments rather than changing game files.
This guide does not provide unsafe network commands or configuration edits. For connection issues that persist, use the official Steam Community discussion page for the app and search for recent reports matching your symptoms.
Low FPS and optimization
Common FPS loss comes from running below the minimum system requirements, outdated graphics drivers, or background processes competing for resources. First, compare your PC against the current requirements on the Steam store page. Then update your graphics driver through the official manufacturer channel. If both checks pass, try lowering in-game graphics settings one step at a time and test in a private room before joining a full public server.
Do not download third-party optimization packs or config files from unofficial sources. Those files can include unsafe changes or claims that do not match the current game version.
Crashes and freezes
If the game crashes or freezes, use Steam to verify the game file integrity first. Corrupted or missing files are a common cause after an update. If the crash repeats in a specific situation, note the map, player count, and what you were doing just before the crash. That information helps when searching the Steam Community discussions or reporting a reproducible issue.
Do not run the game as Administrator or change system permissions unless the official support pages specifically instruct you to do so.
Voice chat and sound issues
Voice chat problems often come from the wrong audio device being selected, the microphone being muted in system settings, or Steam voice settings not matching your headset. Check Windows or Steam audio settings before changing in-game options. If sound effects work but voice does not, the problem is more likely an input device than a game file.
If voice chat is important for your group, test it in a private room before a larger session. A quick audio check before the match prevents the frustration of trying to troubleshoot while strangers are waiting.
Painting tool or eyedropper not working
If the painting tool, color picker, or eyedropper does not respond, first check whether a key binding was changed or another overlay is capturing the input. Try the basic painting controls in a private room with no other players. If the tool still fails, verify the game files through Steam and check the Steam Community discussions for any recent notes about painting tool issues after an update.
Do not trust downloads that claim to fix the painting tool with modified game files. The safe path is the current Steam support route.
Dedicated server and private server notes
Setting up a dedicated or private server may require separate server tools, network configuration, and port forwarding. This guide does not provide server setup commands because requirements can change with game updates. For dedicated server instructions, search the current Steam Community guides and official game pages. If you only want a private game with friends, use the in-game private room feature rather than setting up a separate server.
What not to trust
Do not trust third-party downloads that promise to fix errors, boost FPS, or unlock features. These are often unsafe and can cause further issues. The official support path is through Steam, the game publisher, and the current Steam Community pages. When an error description from this page becomes outdated, the safest action is to check the live Steam Community or official support page for current information.
What to do after troubleshooting
If you fixed a connection or performance issue, test in a private room before joining a public server. If you are organizing a group night, confirm that everyone can connect and hear voice chat before the first round. If the problem is not technical but about understanding the game, return to the how to play guide. If you need custom stages, use the Workshop guide and verify current map information on Steam.
