Saw this topic in 2016 but it just happened to me now. I can access Tidal using credentials through Tidal app and online.
Same here. Changed password at Tidal (which I can log into) and still a no go in Roon
This happens to me occasionally. Going into Settings/Services and disabling and then reenabling the Tidal service seems to work, then logging in again. Just putting your password in again doesn’t seem to work. Even though I know the password is correct, it doesn’t take it.
Don’t worry. Disabling Tidal doesn’t destroy anything. Re-enabling pulls all your favorites back in.
Reboot your core machine
Rebooting resolved this issue. Thanks.
