Just to note, this is the exact same error I am/was discussing here: https://forum.sector3studios.com/index.php?threads/dedicated-server-inconsistent-connection.5070/ Glad you got a screenshot of it as I had forgotten to
So over the last few weeks I've noticed this seems to happen, for me, around 6:00 PM Eastern Time (GMT - 5) each Thursday. My connection to R3E overall remains constant and unhindered, as does my overall internet connection, but my connection to the dedicated server portion seems to fail at this point. Makes me wonder if it might be some sort of routing/timing issue with the backend/host/authentication server in particular.
