I got the same message on my stationary computer at home last night.
I used my automatic fill in of credentials and it used my email address.
Yet the reply I got that my username was not allowed to log in from that IP.
Now I’m back home again and tried logging in.
No change to my system what so ever compared with yesterday and this time I was allowed to log in. Strange.
Dear users,
I’m sorry that we are experiencing those problems. It’s because of bugs in Discourse (our forum SW) upstream. There is a new version on the way and we are planning to install it tomorrow, I have a faith that it’ll help.
I am suddenly getting this problem trying to log in from work, though I was able to last week just fine. Fortunately I can still log in from home. Is there a real solution to this issue?
