After update jitsi shows: You have been disconnected. you may want to check your network connection...

After rebooting the server because of an update, jitsi is inusable. It shows the initial screen, but when I try to log into a session I only get the message "You have been disconnected. you may want to check your network connection"
I purged jitsi via helm uninstall video and set it up new, but it doesn't change anything.
Then I set up a new teamserver with nextcloud and jitsi. Landingpage and nextcloud are ok, jitsi stays broken.
It seems to me that an update from jitsi broke the the helm install script for jitsi.

Need help!

greetings

Start by reproducing the failure in the teamserver deployment and reviewing the Helm installation script used for Jitsi, especially after an update or a helm uninstall/install cycle. Confirm the cause and make the deployment usable again when joining a Jitsi session, then verify the landing page and Nextcloud still work.
