Trying to use Caddy behind Cloudflare (with caddy plugin), Caddy itself starts fine and listens on ports 443 and 80, but trying to load my-site-name.net fails on all browsers with error ERR_TOO_MANY_REDIRECTS.
My /etc/caddy/Caddyfile:
my-site-name.net
root /var/www/
tls {
dns cloudflare
}
My /etc/systemd/system/caddy.service.d/override.conf:
[Service]
Environment="CLOUDFLARE_EMAIL=my_email_address@gmail.com"
Environment="CLOUDFLARE_API_KEY=1234_my_cloudflare_global_api_key_4321"

As far as I’m aware I’m not trying to do anything spectacularly complex. I tried setting CLOUDFLARE_API_KEY to the key listed on cloudflare as ‘Origin CA Key’ but this prevented Caddy from running at all.
I also tried making a single label for my-site-name.net and nesting the rootdir and tls directives within in, but it made no difference.
Am at a bit of a loss.
