IIRC, the Tidal tokens are issued at login to Tidal and are valid for a set period of time (eg 1 month). All communications to Tidal require this token to work.

So your token will just expire one day with no warning and Tidal will stop working.

You may have 'renewed' your token just a day or two before they stopped this authentication method; hence it stop working for different people will be at different times.
