I've had this issue (tracks abruptly terminating and track skipping, followed by the "networking/connectivity" message) with Tidal over Sooloos for years. I've been unable to isolate any particular issue, having tried all the usual suspects and obvious network-related remedies. (Also, setting aside the "track not available" thing--Tidal loses the right to carry albums, or changes up the links to them, on a fairly regular basis, although I listen to a lot of indie stuff, so maybe more widespread there.)
However, I've not yet encountered track terminating/skipping with Tidal over Roon.
