Central Shows firewall in firewalls, but not in licensing

same here

Essentially: Firewall Management is different from Firewall Licensing. 
The firewall is currently claimed (after migration from MySophos to Central) to the Central Account, you see in the Firewall. Check Firewall - Licensing. You will see an Email + Account name. This data is from a Central Account. 
Try to check, if you know the account, which is used and try to get access to this Email Address. Try to login/sign in to this Central Account - Then you can transfer the Firewall to your destination account. 

If that fails, you can create a customer care case to figure this out. 

Hi LuCar Toni ,

i have two XGS2300 in HA correctly listed in Sophos Central > Firewall Management > Firewall

In Sophos Central > licensing > Firewall licenses i haven't firewall listed, "no claimed firewall to show" but if i try to claim one of the firewall it says "the firewall is already claimed"

I confirm that in the firewall web interface the license is associated with an email address different from my account.

This email address was not a central account until now. I just added this email address as a central admin account of our organization but if i enter in Sophos Central > Licensing > Firewall licenses i have the same problem: no firewall listed and "firewall already claimed" if i try to claim it

This is because the email address was not a central account when Sophos migrated the firewall from MySophos to Central?

I must then create a customer case for fix it?

Thanks

You should have got an Email back in the day to register this Email address as a Central Account. It might be stuck or already invalid. 
Your next step should be customer care account to get this fixed and moved to the right account.
