Hello.
I have an issue for like a week.
When I try to login I recieve error: The information you have entered is not valid.
I tried to change password couple of times. It didnt help.
"Your current connection is not on the whitelist." is in profile-overview. But that was not mandatory a week ago as I remember. Seems like login server rejects my requests.
I searched the forum for tips. All other topics have different issues

I'm getting this as well. Just signed up. Did some googling. Can't figure out what's going on. Is my username meant to be in all caps? Cause that how it looks in the email that was sent to me.
