Can't see any graph pages (only device pages) after upgrading to Ubuntu 21.10

After an Ubuntu kernel upgrade to 21.10, I can no longer access any graph pages from the Web GUI.
Device pages come up without issue, I can even hover over a graph and get an image.
Click on the graph returns a page that says “This site cant be reached” and the ip address cannot be found.

Validate.php returns look fine
