Using firefox to access server gives header and nothing more


I have trouble accessing the server using Firefox on Linux.

All I get is the black header with the logo. No login fields.

The following output is in the debug console, but I don’t know if it’s the actual cause:

This page uses the non standard property “zoom”. Consider using calc() in the relevant property values, or using “transform” along with “transform-origin: 0 0”. [](

Source map error: Error: request failed with status 404 Resource URL: Source Map URL:

(note that when I copy the url from the error message in a new tab, it loads correctly)

I have Firefox 86.0 on Ubuntu 18.04.

It works when I use Chrome on Linux and also when I use Firefox on Android.

What may be the problem??

Best regards,

Sorry, this can be wasted… After a reboot of the server I am now able to access it from from Firefox as well. Must have been a temporary hick-up…
