SQL Clone working for one, forbidden for other

Hi,

I'm having some issues getting the SQL Clone up and running for a specific user. The agent is installed on the device with administrative user and when logged on with user A it works perfect. SQL Clone sees the machine, its green and we're able to put clones there. When the agent logs on with user B, the machine stays red and logs show below errors:

Independent task '"AgentServiceTask"' failed

System.Net.Http.HttpRequestException: Cannot contact SQL Clone Server at ******** Check that SQL Clone Server is running and the agent is correctly configured. ---> System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: The remote server returned an error: (403) Forbidden.

and

Error isn't known to be transient, not retrying

System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: The remote server returned an error: (403) Forbidden.

   at System.Net.HttpWebRequest.EndGetRequestStream(IAsyncResult asyncResult, TransportContext& context

Both users are AD users with membership in exactly the same AD groups.

Rights are managed via these AD groups so they should match.

Both users have same access rights on the image directory, again arranged via AD groups

Both users are local administrator on the machine and sysadmin in the SQL server instance

Privilege to perform volume maintenance tasks is enabled for administrator role

Users are compared on the same machine with the same agent.

Anybody any idea why its not working for user B? Identical users, identical rights same machine but working for only. Events on SQL Clone Server don't show any errors.

Regards
