It's two config lines to use your own reverse proxy. Put the stack on 80 internally so it doesn't do certs and set a host port. That's simpler than some other services... how can this be easier? > > > > You only have to set FLUXER_CADDY_SITE_ADDRESS=:80 And pick whatever you want for the Caddy port. 1234:80 done. > > > > > > > > > I assume this is a different issue? > > > image > > > > > > Yes. I've been using the aforementioned method to put Traefik in front of Caddy without issues. > > > Weird as i get the same error when i use the http link.... Is there anything useful in the browser console on container logs?
