Here's how to Fix Steam Auth Timeout on Rust and other games.
Here are some things you can try to fix the Steam Auth Timeout error in Rust and other Steam games:
- Restart your computer and launch Steam again. This resets connections which may fix temporary network issues.
- Verify your system clock is set to the correct time. Being off by several minutes can cause auth errors.
- Disable any VPN or proxy software temporarily to see if that is interfering.
- Reset your router and modem to refresh internet connections.
- Verify your firewall, antivirus or security software is not blocking Steam. Try adding exceptions if needed.
- In Steam, go to Settings - Web Browser and delete web cache/cookies. Then restart Steam.
- In Steam, go to Settings - Downloads and check for corrupted files. Have Steam re-download any affected files.
- Completely uninstall and reinstall Steam. This wipes all cached files and starts fresh.
- As a last resort, create a new Windows user account and install/test Steam there to see if it works properly. Helps determine if it's a system or account specific issue.
- Check Steam forums/status page for any known server issues. Sometimes outages can cause authentication problems.
