SOLVED: Jellyfin & Caddy not working

[Ghostly_Ghost]

So I have followed the instructions in this guide (https://forum.jellyfin.org/t-access-your...with-caddy) to try to get Caddy working with my Jellyfin, but it's defeating me .

Current set up - Jellyfin 10.10.6 is installed on a Fujitsu Esprimo 556 running Ubuntu Mate.  Not using docker for JF.  I installed caddy and before I edited the caddyfile when I entered jellyfin.mydomain.net I got a page saying caddy was installed and working.  I altered the caddyfile and it's all gone pear-shaped and I'm tearing my hair out 

Here's the caddyfile contents:

Code:

# The Caddyfile is an easy way to configure your Caddy web server.
#
# Unless the file starts with a global options block, the first
# uncommented line is always the address of your site.
#
# To use your own domain name (with automatic HTTPS), first make
# sure your domain's A/AAAA DNS records are properly pointed to
# this machine's public IP, then replace ":80" below with your
# domain name.

jellyfin.mydomain.net {
reverse_proxy 127.0.0.1:8096
}

# Set this path to your site's directory.
#root * /usr/share/caddy

# Enable the static file server.
#file_server

# Another common task is to set up a reverse proxy:
# reverse_proxy localhost:8080

# Or serve a PHP site through php-fpm:
# php_fastcgi localhost:9000
}

# Refer to the Caddy docs for more information:
# https://caddyserver.com/docs/caddyfile

When I try to access jellyfin.domain.tld I get this (screenshot from firefox)

Please help before I go around the twist!
