sdrplay RSPdx-R2 device visible on server but not remotely from a client

[JoeTester1965]

Have installed all the latest software and drivers but still a 'SoapySDRUtil --find' command works fine on the server for a sdrplay RSPdx-R2 device but is not visible using 'SoapySDRUtil --find="remote=192.168.1.50, driver=remote' from the client (but my RTL dongle is OK).

Any ideas what could be causing this, in particular is there an extra step needed to enable remote functionality for the sdrplay device to get a remote option like the RTL SDR?

Thank you.
