Hi @Gregory_Itingen,
Apologies for the troubles here! Typically a reboot of your Core will resolve this type of behavior but since that didn’t help here please see the instructions below:
- Stop RoonServer on your Core, find your Roon database and delete the tidal_account file (Database > Registry > Core > tidal_account). Once you do this try to login again.
- Check that your account is still active, as suggested here. In the past we have seen that you may be able to login to the TIDAL account in the TIDAL app, but the subscription itself may not be active therefore cannot connect to Roon.
