CSS not loading due to wrong MIME type

Help

1. The problem I’m having:

CSS is not loading on my fileshelter site due to wrong MIME type. Everything works normally otherwise.

2. Error messages and/or full log output:

3. Caddy version:

v2.6.4

4. How I installed and ran Caddy:

a. System environment:

Installed from epel repo on AlmaLinux 9.2 x86_64

b. Command:

systemctl start caddy

c. Service/unit/compose file:

Using the default systemd unit file.

d. My complete Caddy config:

https://vps6.dedyn.io {
    redir /jellyfin /jellyfin/

    handle /jellyfin/* {
        reverse_proxy 10.8.0.1:8096
    }

    redir /files /files/

    handle /files/* {
        reverse_proxy localhost:5091
    }

    handle {
        respond "You must've lost your way, wanderer!"
    }
}

Since you’re proxying to serve those files, this isn’t a problem with Caddy. Whatever that service you’re using is, is to blame.

It’s probably not designed for serving files for a website, but only meant for file downloads.

It seems to work just fine over http, and also in a subdomain over Caddy. This however is a DDNS site, so I have to do subfolder. The settings of this app has an option to enable reverse proxy support, and this is happening with that on.

Okay, then that app is missing a feature to support being run under a base path. You’ll need to ask them to add support for that.

That said, are you sure you can’t use a subdomain? Try files.vps6.dedyn.io. Or use DuckDNS instead, which definitely has subdomain support.

It does have that option, which is turned on. But maybe it’s buggy, I’ll open an issue on their GitHub.

It doesn’t work.
(Edit: Looks like it does. I just needed to create a separate CNAME entry.)

Thanks, I’ll check it out.
