Cannot login on testserver

I have 3 accounts that I can play on Tranquility, but I cannot login to a single one of them on testserver - client claims Invalid username/password.
The accounts are more than a year old, the login information was not changed for quite some time and works on the live server.
Anyone experiencing similar problems?

Edit: Its working again
Looks like it was only a temporary problem, thx at CCP if anyone fixed it.
Restarting the PC and client did not fix it before

are you on steam?

No, my eve client is not connected to steam.

If you hadn’t changed passwords since 8-10-21 then it may be a bug and you could have access to the next mirror after Nov/Dec. They won’t randomly fix someone’s account on sisi.

I can’t login either.

It gets into the client, throws up an “Incompatible (Release)” error and that’s it.
