Subdomains on Tailscale Funnel mess with css and js

I’m trying to setup a webserver through Funnel using a subdomain, and it encounters an error where the css and js files cannot be found because of the subdomain.

Command used:

sudo tailscale serve https /compreface

tailscale serve status output: (Funnel on)
|-- /compreface proxy

Response from trying to access the webpage:

Is there any way to configure funnel to be able to access these files? The only way it currently works is if there is not subdomain, like:

sudo tailscale serve https /

output: (Funnel on)
|-- / proxy

which makes sense but also limits me to only being able to serve one webserver. Are there any other ways to host two webservers at once?

Current Tailscale version, since the devs change around Funnel commands: 1.38.1
Environment: Ubuntu 22.04.2

Did you ever get this working? I’m having exactly the same problem.

Or did you find some other way to access different services on one host through tailscale? I need this for the HTTPS certificates.
