[2019] Having problems logging on to favorite servers

Hey @marauder6307

Welcome to our community.
You mention this is happening with mods installed. Could you test if this issue happens when having all mods disabled and joining a vanilla server?
If it doesn’t happen, it’s most likely caused by an out of date mod.

Glad to hear you found the culprit. Thanks for keeping us updated.
Just in case it can help other players in a similar situation in the future, what AV software was causing this issue?
