Hi,
I’ve been trying to fix this problem through 2 PCs now. On my old PC, I had Minecraft and Avast running, no problem, then suddenly after an Avast update in June I got a login error on Minecraft that wouldn’t allow me to play online. When I tried uninstalling and reinstalling Avast, Java and Minecraft, I couldn’t even get logged back into the Minecraft server due to an authentication error. (yes, all my login and password credentials were correct).
So I now have a new PC, uploaded Minecraft and Avast. Both ran just fine for about a month, then on Aug 8th Avast did another update and I can’t login to the Minecraft servers, can’t play the game online. I tried logging out and back in on a separate user name and can’t, so if I uninstall Minecraft I will be completely locked out of the game again.
I tried adding exclusions to the Minecraft launcher and the java files in Avast, nothing works and no one seems to be able to help. Does anyone have an answer? I play with my family online. It’s very frustrating. :-\ I’ve included the log from the Minecraft launcher with the errors below:
