Error Message = Cannot index into a null array.
Fully Qualified Error ID = NullArray,Get-ResourceString

Otherwise here is the SolidCP error on the GATEWAY server:

Can you help me?

Thank you.

Best Regards.

Hello,

Can i firstly check which version of SolidCP you are using? v1.1.1 to v1.2.1 has alot of RDS fix's made inside it, So i would highly recommend the latest version.

Can you confirm if the SolidCP Server user on the gateway is a member of the domain with Domain Admin rights? (you will need a iisreset if you alter the groups).

Thanks,

Trevor Robinson
