Remote "Failure to Connect"

Continuing the discussion from Remote response time poor / response failure : v1.1 [Remote Connection]:

I installed Roon on my IMac. Im currently building my library…134,000 tracks and counting. However when I try to connect remotely through my Dell laptop or IPad Pro, it sees the network, but I get a “communication failed” notice. How can I fix this?
