Could not log in to World of Warcraft at this time.

Problem as title states: https://imgur.com/a/C4l62QJ

I was logging in a few accounts to try out multiboxing and one of them suddenly froze, upon restarting the client I was unable to log in. Tried looking around and have done the fix to add Warmane to my exception list in Firewall, checked my realmlist, deleted my WTF and Cache folders, and restarted my computer countless times. If I'm missing something, someone please enlighten me as I've never had this issue before over the years. Thank you and hope y'all have a good day.

Same issue here, started happening about a week and a half ago. It is probably a server side issue since there are a lot of threads about it in the past week, but it would be nice of someone to explain it at least. It prevents players from participating in raids which is a big no no. For example, yesterday I was in ICC 25hc/nm, and in the middle of the LK fight I got disconnected and couldn't log back in...a big bummer.
