--- Comment #20 from Sveinar Søpler cybermax@dexter.no --- (In reply to David Koolhoven from comment #19)
I sent a version of the patch into the patch list. I'll update if it's accepted or rejected.
It seems as wine-6.12 (and also wine-staging-6.12.1) completely broke Battle.net connectivity, so it is kind of hard to test if any new patches that fixes this particular wineserver problem is being implemented.
Have you tested wine-staging-6.12.1 and see if you can log on? (Kinda seems as it is waiting on Agent.exe update, but not easy to see). Log from Agent.exe
Wine-6.12:
[I 2021-07-04 12:43:40.0322] Handle Event: "update agent event" [I 2021-07-04 12:43:40.0322] Checking Network Connection status to http://us.patch.battle.net:1119/agent [I 2021-07-04 12:43:40.0852] Network Connection Response to http://us.patch.battle.net:1119/agent - CURL error: 0, Status Code: 404

If Agent.exe cant connect = no dice afaik.
