ARC demands Non-Existant Server Upgrade

[Suedkiez (Just a fellow user like you)]

If your versions are up to date (and you are not trying to run a mix of Early Access and Production versions on server and remotes), then this is a new issue that has recently affected several people. See this thread:

Roon Server cannot connect with this version of ARC [Ticket In; Resolved with ARC Reinstall]

Hi @Rives_Bird, Thank you for the report. There’s a ticket in for this behavior with development. Do you have an approximate timestamp of when you first encountered this issue, or when you last experienced it before the reinstall resolved the problem? Development would like to activate diagnostic logging to inspect what went wrong with ARC. We’ll use our findings to prevent recurrence of this issue for you and other users moving forward.
