I have managed to get the API to no longer disconnect.
But reviewing the plug in logs i'm getting a 403 error reason : cuts off .
Downloaded log file and i get the following errors
2022-06-21T10:43:50.5813137+01:00 [18.104.22.168] SophosService :: ERROR 2022-06-21T10:43:50.6526954+01:00 [22.214.171.124] SophosService :: ERROR 
Will upload log file if needed
If this is because this is a sophos enterprise tenancy .please advise when the integration will work with and enterprise tenancy
