Hello,
The error would indicate that the Enterprise server is unable to connect to the RDS Gateway.

I would double check it shows a version number in Configuration -> Servers  then select the server.

If that works fine check that the SessionHost is pingable from the Gateway.

Finally i would check in the Windows eventlog under Application -> SolidCP to see if a more detailed error has been logged.

Kind Regards,

Hi Trevor,

Have you got any update on this issue?

Thanks in Advance ?

Hello,

Can you confirm that the Root OU set in the RDS Provider has been set and does exist on the AD?

Kind Regards,
