I haven't played since 2021 and played on the blizzard client before it went to steam. I've been attempting to get back into the game recently though whenever I've attempted at connecting to the servers I get the same error as listed in the title. I've attempted multiple guides on swapping my DNS server although neither work at all. If someone could please help me by figuring this out or has an idea that would be wonderful. Unfortunately this horrible game doesn't allow you to submit support tickets regarding technical issues I hope someone might have a better solution for me. Thank you.
