This issue was automatically created by Sentry via [Explorer Alpha Github Issue Creation](https://sentry.io/organizations/decentraland/monitors/alerts/3130340/)

Start at Assets/DCL/Multiplayer/Connections/Archipelago/Rooms/ForkGlobalRealmRoom.cs line 46, where ChooseRoom reports the failure, and trace the ws-room URL from StartAsync. Reproduce the Sentry exception if possible and inspect the related room connection flow; done should mean this URL no longer causes the reported protocol-determination exception.
