LIcense server problem?

When I start SU 2022, I get this message:

Nous rencontrons des difficultés techniques
La réponse du serveur d’abonnement n’est pas valide
Ajouter une licence classique

Which can be translated as:

We encounter technical difficulties.
The subscription server answer is not valid.
Add a classic license.

Anyone has an idea ?

SU 2022 was working nicely a few days ago.

SU 2021 is working OK.
