i was just trying to playa little bit after a long day and this error start ocurring out of nowhere, is there any possible way to fix?
Are you getting it repeatedly even after doing this ^ step?
Yes i try almost every fix that suggest on the forum, from cache, WTF delete, ipv6 config through cmd, reinstall the game, battle net cache, all of then to no avail.
Your client likely needs updating. Fully shut down the computer for a few minutes, then try a Scan & Repair if the update doesn’t popup after loading Bnet again.
