Since the July 14 update, Arena has intermittently become stuck on extremely long loading screens and then fails to join matches. Restarting Arena and completing a full login temporarily resolved the issue, but it returned about two hours later in the same session.

The attached log shows failed access-token refresh attempts (Error refreshing access token... Error: -1), followed by Account login did not happen, failing SocialService init. Arena subsequently submitted matchmaking successfully and connected to the match server with normal latency, but the server rejected the session with MatchServiceErrorCode_NotAuthorized and Authentication failure. Matches and other API requests work normally until the authentication state fails, so this does not appear to be a general connection or latency problem.

Platform: PC
Arena version: 2026.61.0.13388
Observed: July 15, 2026, approximately 6:54–6:58 PM CDT
Expected: Arena should refresh authentication and remain logged in throughout the session.
Workaround: Restart and sign in again, but this only provides temporary recovery.
