ARC Raiders error ARAU0287: login authentication failed (fix)
Logging in throws an "ARAU0287" error and the game won't get past authentication, sometimes happening on every attempt to launch.
Also appears as: arau0287, arc raiders error arau0287, arc raiders login authentication error, arc raiders authentication failed
ARAU codes are Embark's authentication-family errors — the client can't establish a verified session with Embark's login servers. Embark hasn't published a specific explanation for ARAU0287 in its Help Center, but a Steam Discussions thread on this exact code, where the original poster said it happened "every login" and blocked them from playing entirely, got a fix reported back by that same player after several days of troubleshooting: antivirus software (Kaspersky, in their case) was blocking ports the game needs, and disabling that feature resolved it immediately. A mismatched system clock or an active VPN are the other causes players and support articles commonly point to for this error family, though neither is independently confirmed for this specific code.
Fix it, step by step
Check whether your antivirus is blocking game or launcher ports
Check whether your antivirus is blocking game or launcher ports — a player reporting this exact error on Steam Discussions confirmed disabling a Kaspersky feature that was blocking ports fixed it after every other troubleshooting step failed.
Sync your system clock and check your region setting
Sync your PC's system clock (Windows: Settings > Time & Language > Date & time > Sync now) and make sure your region setting matches your actual location — commonly reported as a cause for this error family, though not confirmed specifically for ARAU0287.
Disable any VPN and restart your router
Disable any VPN and restart your router before relaunching.
