Reverse proxy for LAN pc's as well as local host

[timelordx]

You can try the approach @openhabgs gave you, It’s a solid solution. You can simplify it even more to:

myddns.org {

    encode gzip

    ## Jellyseer    
    redir /seer /seer/
    handle_path /seer/* {
        reverse_proxy 192.168.1.9:5055
    }

    ## Jellyfin
    redir /fin /fin/
    handle_path /fin/* {
        reverse_proxy 192.168.1.5:8086
    }

    ## Drop everything else
    abort
}

Then, you can access both via:

https://myddns.org/seer
https://myddns.org/fin

However, some web apps do not like to share the same FQDN with other web apps:

The "subfolder problem", OR, "why can't I reverse proxy my app into a subfolder?"

Have you ever tried to reverse proxy an app into its own little subfolder of your domain name? Makes things neat, doesn’t it? Using example.com/foo/ for one app, example.com/bar/ for another. If you’re coming here from one of the selfhosted communities, you might be thinking along the lines of example.com/sonarr/, example.com/radarr/ etc. Chances are, you’ve tried some configuration along these lines: example.com { redir /sonarr /sonarr/ handle_path /sonarr/* { reverse_proxy localhost…

If that’s the case here, you need either two FQDNs, or the same FQDN but each web app on its own port.
