Sophos Central Login no Login possible

Hi , 

i´m struggeling with the Sophos Central Login.

I can´t login in Sophos Central with my Sophos ID , a reset did not work either.

I can Login on https://secure2.sophos.com/ with my id but not in the central login.

Here after i type in the credentials the notication occurs 

"Authentication failed. Check your credentials and try again."

On a password reset , i type in the verification code which was send on my Email-Adress and then after i type the new Password ,the Message popup that the

authentication has failed ,check the credentials .

So i´m a Sophos XG Home User and want to migrate my AP to Sophos Central since the Basic Wireless Protection is now free.

I don't know how the support for XG-Home works since it is not a paid license.
Therefore the question here in the community forum

I searched on the web for a fix ,but nothings seems to work .

maybe the problem is related to the merging of Sophos accounts ??

Thanks a lot
