Constantly disconnecting from panel

Lately I’ve been running into an infuriating problem where the panel constantly logs me out after just a minute or two. Sometimes it won’t let me save changes to a blog post or if I switch to a different page it brings me instead to the login window. Is it a setting within Kirby that I’m not aware about doing this or might it be something to do with my host?

Have you made any changes to your installation lately which might have caused that? If not, maybe your provider has changed something.
