Qobuz problems "network connection"

Hello, same for me here in France as a new user of Roon today, impossible to have a validation of my credentials to connect to Qobuz. No problem with Qobuz app on my mac.
Everything has been disconnect and reconnect and no Qobuz

Have you rebooted your Roon Core machine?
And ensure you are logging in with your email address and not a username inside of Roon.
