Everything was working fine until pre patch event started yesterday, now everytime I try to connect I get all realms in red with an incompatible label, what happened?, how can the game break on its own without me even touching anything?
The client needs to be patched.
Probably restarting the computer would handle it.
Had to reinstall battlenet app, for some reason it showed the game as patched even after verifying files and checking for updates, after reinstalling there was like a 90mb download and it fixed the issue
