Caddy fails to obtain Letsencrypt certificate

Caddy fails to obtain a LetsEncrypt and gives the following error:

        Validation for [my sub].[domain].net:80
        Resolved to:
                [my ip here]
        Used: [my ip here]

This is my Caddyfile:

[my sub].[domain].net {
        proxy / 192.168.1.10:8080 {
                transparent
        }
}

Have I missed some configuration needed in the Caddyfile?

I am running the ,latest docker image from abiosoft as of today (2017/07/03)

This usually means something else is responding to the challenge on port 80. Make sure your ports and DNS are configured properly.

[fbjerggaard (Frederik Nielsen)]

Ports and DNS is configured correctly and I have verified that by starting Caddy up and forcing it HTTP only it works

[fbjerggaard (Frederik Nielsen)]

I messed up the port forwarding on my Mikrotik router - messed up something on the target ports… So all is good now

Told ya

Glad you figured it out!
