ARC Raiders error AREX0001: disconnected from raid (fix)
Mid-raid, the game drops connection and shows "AREX0001" instead of reconnecting — sometimes a "Reconnect Available" prompt appears but tapping it throws the same error, leaving you stuck outside the raid with your gear still inside it.
Also appears as: arex0001, arc raiders error arex0001, arex0001 connection lost, arc raiders disconnected from raid, arc raiders lost connection to game server, arc raiders reconnect available not working
AREX0001 is an in-raid connection failure — your client loses its live session with the raid server and can't re-establish it. Multiple independent Steam Discussions reports describe the same pattern: it starts or spikes right after a patch or hotfix, hits players mid-raid with no warning, and often leaves them unable to reconnect at all, which means losing whatever gear and loot they were carrying. There's no dev acknowledgement of a specific cause found yet, and no confirmed fix — this is a server/client-session problem, not something you can prevent locally.
No problems reported in the last 15 minutes.
Is ARC Raiders down right now? Live reports →What to try
- 01Check the ARC Raiders Steam news hub and the @ARCRaidersGame account on X for an active known issue or hotfix before anything else — several AREX0001 spikes reported on Steam Discussions line up with recent patches, not local problems.Reported
- 02If a "Reconnect Available" prompt appears, try it immediately — some players report it works within the first few seconds and fails once the window closes.Unconfirmed
- 03If reconnecting fails and you're kicked to Speranza, don't requeue with valuable gear until you've checked whether other players are reporting the same error at the same time — a cluster of reports means it's Embark's servers, not your connection.Reported
