Stuck on Connecting indefinitely when trying to enter Lordaeron

Greetings. I was playing here since November 2019, all was fine until now.
Yesterday, 04.12.2020, when trying to connect to WOTLK Realm Lordaeron, just got stuck on "Connected", with no queue place etc., no matter how long I wait. I thought that it was temporary issue, but no, on the next day, 04.13.2020, happened the same thing, just stuck on Connected.
I can normally login on all other Warmane WOTLK servers, same as before, checked it many times. EXCEPT Lordaeron for some reason! And it is no matter if there is a queue on Lordaeron, this moment there is no queue and I cannot enter all the same. Tried to delete Cache-Interface-WTF, no effect. In result, I cannot login on server I normally play on.
What can possibly cause such an issue? How it can be resolved?
I thought I could create a ticket on this issue throughWarmane Armory - Support, but there seem to be only Ban Appeal category of tickets. Is it possible to adress GM (or someone else who can help) with my issue?

Update. Problem persists after server restart. Anybody knows, can this be because Lordaeron's IP address is unavailable for me (for some reason)? What if server IP is blocked, what error do you get when trying to connect?

And if this is some Account related problem (like server cannot load list of characters), who and how can solve this? I have 10 characters on Lordaeron, there is of course no ban.

Have same problem, am stuck on connected screen but not logg to chars list, do u have solution?

Same problem, ¡please help us!
