Connection 3901 error

I've got that error on Ahkma, so I tried on Torian, but after level 22 I got the same error.

Mention that I can connect to the other servers.

Anyone has encountered this error before can lend me a hand fixing it?

tyvm =)

why oh why are you asking this here and not on the MAIN forum, what the hell do you think?? we are the devs or something?
this is not an issue for here its an issue for tech support from YNK.
