Error syncing initial 2nd domain, wont retrieve any endpoints

[FortinKnight]

Getting the following errors when trying to add a 2nd domain. 1st domain adds and syncs fine and it locates the endpoints.

Testing the 2nd domain is successful and i save the config, just than you try and do a manual sync it keeps failing with the 2 errors below and no endpoints are found.

Forticlient EMS version is 6.2.4 build 0894
