Hello there,

Thank you for contacting the Sophos Community.

Are you trying to access using the FQDN or the Public IP of the XG? Try also using incognito mode, as sometimes the browser might cause issues after a new certificate for frequent site changes.

Hello Stefano,

Thank you for the follow-up.

Can you send me a PM with the FQDN of your firewall?
