Dear Sir:
Just upgraded to V3.1.1 and use normal TCP connection is fine, but if I use SSH for the panel connection, when I click any button eg.create I get 500 Internal Server Error.
May be SSH need additional configuration but how could do this ?

Best Regards,
Paul-LKW

Nevermind, on debian systems, the group is libvirt and by adding the webvirtmgr user to that group, its solved the problem.
