New XG 115 keeps dropping the connection

I am a new Sophos user and wanting to move over from my old Forti device to Sophos XG 115

My XG keeps dropping the connection, only basic config has been done. The Lan to wan built in rule is the only rule configured.

when i RDP to a remote server i continually get this error

When i plug in my old Forti, it does not drop connections
