Can't create a Central Account

I'm trying to create a Sophos Central account.

First I had to do is to "Create a Sophos ID". After I confirmed the mail address entering the code, the screen appeared and persists:

"One moment while we sign you in..."

I can confirm that I can login to "My Sophos" with this credentials now but I can't login to Sophos Central.

Regards,

Dominik
