How annoying it can be when, right in the middle of diving into the post-apocalyptic world of Arc Raiders, you encounter the ARAU0297 error. That online connection error means a failure to communicate with the game’s servers and prevents access to matchmaking and other online services.
Before you resign yourself to a session of troubleshooting instead of raiding, here is a guide to the most effective fixes, curated from community reports and technical analyses.
How to Fix ARAU0297 Error in Arc Raiders?
The most surprisingly successful and widely reported solution involves your system’s date and time settings. You see, the game’s servers need a very precise time sync for authentication, or else they can reject a connection.
To sync your system time on a PC:
- Go to Time & Language settings.
- Toggle the “Set time automatically” option off and then on again.
- For good measure, click the “Sync now” button to make certain your clock is perfectly aligned with server time.
This simple step has resolved the ARAU0297 error for many players across all platforms.
If the time sync doesn’t work, then you need to check for network-related issues. Flushing your DNS cache will remove old or corrupted network data that can affect the connection.
To flush your DNS on a PC:
- Open the Command Prompt as an administrator.
- Type the command ipconfig /flushdns and press Enter.
- You can also use the following commands for a deeper reset: netsh winsock reset and ipconfig /renew.
Other possible solutions include checking the integrity of your game files through your game launcher, checking that your firewall or antivirus isn’t blocking your game, and turning off any active VPNs, known to cause conflicts with games.
