What happens with jitsi when ssh access is off?

Well, it seems that anything changed with my linux server … allthough I did not change any setting. With timeshift via terminal it was possible to restore a backup. Now I deactivated the ssh access because the server-administration is easy to handle direct with monitor and keyboard. Does this have any effect on the function of jitsi? Thanks for your answer/info

Not at all. Jitsi itself doesn’t use SSH for anything.
