Using firefox to access server gives header and nothing more

Hi,

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”. [192.168.68.122:55414](http://192.168.68.122:55414/)

Source map error: Error: request failed with status 404 Resource URL: http://192.168.68.122:55414/css/bootstrap.chash-2f624089c65f12185e79925bc5a7fc42.min.css Source Map URL: bootstrap.min.css.map

(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,
Vic

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…

This is not a big deal as I have a workaround, but I have encountered the same issue as vimortelmans’ with the similar warnings/errors.

I just upgraded my Ubuntu server from 16.04 to 18.04 which is where my UrBackup server is running. I try to access the GUI via Firefox and only the header and footer load with a loading progress bar going across the screen at the top and the mouse turns into a spinney wheel when I hover over the contents of the page.

I get similar warnings/errors on the same js file as vimortelmans above plus another file when I access from Firefox (version 95.0) from a Windows 10 (version 20H2) machine. The GUI works fine from Chrome (Version 96.0.4664.93).

To see if it is a OS issue, I also tried on Android (version 11) via Firefox (version 94.1.2) and Chrome and again only Chrome works. Seems to be a browser compatibility issue with the login screen.

Also tried updating the Ubuntu server and was able to get to the following Apache versions:
apache2-data (2.4.29-1ubuntu4.20)
apache2-utils (2.4.29-1ubuntu4.20)
apache2-bin (2.4.29-1ubuntu4.20)
apache2 (2.4.29-1ubuntu4.20)

Here are the warning/errors I get on Firefox:

The errors from Chrome:
