1. The problem I’m having:
Caddy + Cloudflare + TLS not working.
I am trying to setup TLS using caddy on a domain name. The domain name is under cloudflares DNS:
On cloudflares side:
- DNS only (grey cloud)
- TLS to ‘Full (strict)’
On my server side I supply the following Caddyfile:
{
email info@DOMAIN.io
}
DOMAIN.io:443{
reverse_proxy 127.0.0.1:8888
log {
output file /var/log/caddy/DOMAIN.io.log
}
handle_errors {
respond "Something went wrong" 500
}
}
curl results:
user@machine:~$ curl -IL https://DOMAIN.io/swagger-ui/
*Stays blank*
When I tried the following configuration everything worked fine but no TLS.
{
email info@DOMAIN.io
auto_https off
}
DOMAIN.io:80{
reverse_proxy 127.0.0.1:8888
log {
output file /var/log/caddy/DOMAIN.io.log
}
handle_errors {
respond "Something went wrong" 500
}
}
curl result:
user@machine:~$ curl -IL http://DOMAIN.io/swagger-ui/
HTTP/1.1 200 OK

2. Error messages and/or full log output:

3. Caddy version:

b. Command:
