Have you confirmed if qBit deploys properly without a VPN enable? If so, you could go into qBit without the vpn and try disabling the "Use UPnP / NAT-PMP port forwarding from my router" in Tools > Options > Connection, then try deploying it again.
Hmm… are you using the community version of Tailscale? Since, I've never had to enable host networking for any of my apps, and I've been able to access all of them through Truecharts Tailscale app while still retaining access to my SMB shares. Also, this may sound silly, but have you double-checked your routes in the Tailscale app?
After looking around, you might be facing an issue with Flatpak permissions. Here's a comment I found on Reddit created by u/avamk where they solved the same issue.
All right, after much trying I installed Flatseal and enabled the Firefox Flatpak's access to my home folder.
After this, it created the expected profile folder under ~/.mozilla/firefox/. I put my custom userChrome.css into that profile folder, and >enabled it in my about:config under toolkit.legacyUserProfileCustomizations.stylesheets per these instructions.
With all of these, the custom userChrome.css is finally working!

Usually when I update it takes no more than 5 minutes max, although I've never timed the reboot process. Note, it's going to depend on your hardware. I'd say, though, if it's been a decent amount of time, and you haven't gotten any sign of it responding (after pinging it, checking the systems' indicator lights, etc.), I'd probably plug a monitor into it and reboot the machine.
The Scale apps documentation, containing a couple of guides for a small set of apps.

Also I highly recommend using Truecharts app catalog. They have an extensive list of apps available, and the support on their discord is excellent, in my opinion, although they also appear to be lacking in the documentation department mostly.
Whoops, you found me. :P
