Sophos Tap App not working in spite of new files downloaded.

i am having issues with the Sophos tap app not integrating stating (Failed to register Sophos Security Solutions for tenant default. Registration Server response: Conflict.) i cannot understand where the conflict is as this is the latest up to date VSAZ file which was sent to us by the Head of Development and API integrations and the same file we have downloaded from the community string which neither worked. any ideas?
