All Roon users with a minimum Linux installation (Debian, Ubuntu), please make sure you have the package ca-certificates installed. Without you cannot connect to Qobuz and Tidal anymore. You get an error “network connectivity errror” when you try to login.
In the logs you get thousands of errors like
