Unfortunately this cPanel will be unavailable for now, even if you could get to the server you would not be able to log as by now the license has expired. Once your account is migrated this will be reflected in the sso login page as you will then be sent to the new DirectAdmin server.
@Anna
speaking of migration, is there any news on x05 yet ?
we have waited going on 4 weeks now to be migrated....
they should be able to provide some timeline by now.
With it already expired, you may need to wait for it to be released fully (they may allow it during a grace period to a higher price), but it would be at the place where you bought it in the first place. I don't know who is your registrar.
