Playing classic WOTLK and have been able to log in via Curse Forge, now cannot - “unable to verify account with that information” addons are still current and work.
Hey there!
We wouldn’t be equipped to troubleshoot a third-party software launch issue since that software is developed by a non-Blizzard entity. If you haven’t checked yet, make sure that your WotLK Classic client is fully up to date in the Battle.net Desktop App. Aside from this, we can only recommend launching from the Battle.net App.
Let us know if you run into any other problems during your adventures. Cheers!
