I am experiencing a similar problem but the message I am receiving is something like “Tidal is loading slowly…”
My setup is fairly simple. My Roon core is my iMac connected via ethernet to my modem/router. My Roon End point is my PS Audio DAC with Network Bridge in a separate room. My internet connection is usually 250 mbps or more.
A wired ethernet connection from the DAC/Bridge to my modem/router is impractical. I use power line adapters. Occasionally they need to be reset but that is not the problem when I get the message I referred to. Also this message is a relatively recent phenomena. I’ve used this setup for at least 6 months before experiencing this problem.
I’ve assumed the source of the problem is Tidal’s servers but would be curious to know what others think.
