WEB-Mail Session expire after approx 5 min - Keycloak-SSO System

Since one of the last Updates users get the massage "Session expired, please login again...".

When the massage is ignored and the page is just refreshed/reloaded ... all works until 5 mins of user inactivity again.

_

What I understand from the logs (also Keycloak´s) is that Grommunio-Web-App only ask the IDP after User Interaction + 5 mins for new Auth-Token.

Idea 1: Is there an easy way to disable this "wrong" message?
Idea 2: Can the Grommunio-WebApp/PHP-Pool/Auth-mechanism be changed to ask the IDP by self if needed?

Try to comment out grommunio.php line #66-#71 leads to Webapp Error "Invalid data received from server"

Thanks for that fast response. "Remember Me" was already on, just dubble checked. System was running since around Februar 2024 with same keycloak settings. Also 5 mins is not every time correct.

here: LOGIN (me) and CODE_TO_TOKEN (Grommunio-Server) 1:12AM ... WebApp close 1:27AM
