I tried changing the Caddyfile config to:

testwiki.nsupdate.info:443 {
        reverse_proxy 192.168.100.5:8080/mediawiki/

But be aware that mediawiki may still respond to requests with /mediawiki in the links/assets, so rewriting may not work in all cases. This isn’t something Caddy can solve on its own. You’ll need to make sure it’s configured to not have a base path configured if you want to serve it from the root of your subdomain. It’s essentially the inverse of the problem described in this article:

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…
