Describe the bug I have set a new wallpaper using Discord CDN's link, it is no longer available since the image got deleted from the channel. Now I couldn't login since it just say an error occured and log me right out.

To Reproduce Steps to reproduce the behavior:

1. Go to 'Settings'
2. Find wallpaper setting
3. Change wallpaper URL to random link
4. Restart kasm server

Expected behavior Wallpaper fallback to normal

Screenshots It's way too fast
