Cannot install any plugins

What is the problem?

I recently updated OctoPrint to Version 1.8.6 and once I did all my plugins went away and I can't seem to install any. I have tried Bed Level Visualizer and OctoPrint-PrintTimeGenius

What did you already try to solve it?

Deleting configuration and starting from scratch

Have you tried running in safe mode?

No

Did running in safe mode solve the problem?

Systeminfo Bundle

You can download this in OctoPrint's System Information dialog ... no bundle, no support!)
