Different problems can end in the same message; the message alone does not identify the cause.
One map, every time: ask for a map-side check. Our operations notes record repeated ASA reconnect loops that cleared after restarting the affected map. A problem with that map or your session is one possibility, but being able to join other maps does not prove the internal cause. Players on other servers have also reported reconnect loops. An admin needs the map, the time and the server log before deciding whether the same recovery applies.
Every server fails: a real connection problem. Studio Wildcard has changed the connection timeouts several times: patch 31.23 "fixed an issue with connection timeouts", 43.18 allowed a longer timeout for players "who take longer for the initial load", and 85.41 fixed a routing issue behind timeouts when using the Cross-ARK transfer system. The official support article names Wi-Fi, a VPN or proxy and old network drivers as causes.
