Ha ha. You are very welcome. As men we are all genetically programmed to not RTFM which is precisely why forums were invented!!! Hope you love the sound. As a total aside I went from a pi3 NAA, to fully optimized PC, and now I am borrowing a microrendu. All I can say is the the hype surrounding the microrendu is true! Now I just need to find some extra money to buy it!
Are you using the same computer for HQP and Roon Core ? If so, then type “localhost” in the IP address field of the HQP Network Zone. This will establish an internal connection from Roon to HQP rather than a connection through your router.
