Active Matter: disconnected mid-raid and can't reconnect (fix)

You lose connection during a raid: the game freezes, drops you to the main menu or login screen, or shows "Login error (authorization error): No connection" or "reconnecting to the profile services... actions performed may be rolled back". Reconnecting either fails or isn't offered, risking the gear and loot you had on you.

Also appears as: disconnected during raid, cant reconnect to raid, connection lost active matter, server freeze active matter, kicked from raid, Login error (authorization error): No connection, reconnecting to the profile services, actions performed may be rolled back

Gaijin's patch notes for 0.4.0.135 list "improved the ability to reconnect to a raid after a connection loss" and "fixed a rare server freeze", and 0.4.0.137 fixed "a rare server error that could occur when a player spawned in a raid." On an older build, update first.

On 21 October 2026 (about 10:20 to 10:45 AM PDT) a login outage kicked players out of raids. Gaijin's community manager said it was "affecting all Gaijin projects right now and not just Active Matter", then that "we had a temporary outage, we've fixed it". Nothing to fix on your side in that case.

    Update to the latest patch. Gaijin's official 0.4.0.135 notes cite an improved ability to reconnect to a raid after a connection loss and a fix for a rare server freeze; 0.4.0.137 separately fixed a rare server error on spawning into a raid.

    If it's a Gaijin-wide outage, wait it out and relog

    If you were kicked to the login screen with an authorization error or the "reconnecting to the profile services" message while many others were too, wait and relog. On 21 October Gaijin's community manager said the outage was fixed and, to a player who lost raid items, that "you should get your stuff back soon - it can take some minutes for the servers to catch up!"
