Caddy http and https on non standard port

Help
1

Hello everyone thanks for all the previous help :smile:

I am just trying to run caddy on non standard port as my development server.

My caddyfile looks like below:

https://helloworld.com:2085 {

root www/helloworld
log logs/access.log
tls admin@site.com
}

I get the below error:

root@abcd:~/ravkumar/caddy# ./caddy -conf caddyfile.conf
Activating privacy features…2017/09/05 20:42:33 [https] failed to get certificate: acme: Error 400 - urn:acme:error:malformed - Error creating new authz :: DNS name does not have enough labels

Looking to resolve this. Could not find enough information about it.

Any help is appreciated !

Is that your whole Caddyfile, unmodified? (We can’t help if you aren’t giving the exact, unmodified text of your configuration.)

Yes… Thats it
root/helloworld has index.html

I cant run caddy on port 80 or 443 as there are webservices already running on them.

That’s odd. What’s your version of Caddy? caddy -version

acme: Error 400 - urn:acme:error:malformed - Error creating new authz :: DNS name does not have enough labels

A label is one section of a domain name. www.example.com has three - www, example, and com. The minimum number of labels for a publicly addressable domain name is 2 (e.g. example.com).

If you haven’t made a mistake while typing https://helloworld.com:2085 in your Caddyfile, there could be an issue with Caddy.

I’m guessing there’s a space between https and ://helloworld.... in the Caddyfile, that’s causing it to be parsed that way, since the Caddyfile posted above should work.

Thanks for the help. There was a missing ‘/’ in https:// ( my apologies for making everyone take a look at that silly error)

Now that is fixed. I am getting the below logs. ( I don’t want Caddy to use the standard ports as I mentioned it is already being used by other services)

caddy -conf caddyfile.conf
Activating privacy features…2017/09/06 04:24:26 [helloworld.com] failed to get certificate: [helloworld.com] error presenting token: Could not start HTTP server for challenge → listen tcp :80: bind: address already in use
root@abcd:~/ravkumar/caddy#

Is there a way that I can force caddy to use something other than port 80 ?

Alright Thanks guys I got it working with cli flag -http-port and tls self_signed in caddyfile.

./caddy -conf caddyfile.conf -http-port 2086

Thanks a lot guys !

Also, I am planning to write a small HOW To article on Caddy server . I hope its okay.

From memory, -disable-http-challenge will turn off validation via HTTP-01 challenge (which uses port 80), and Caddy shouldn’t bother binding it in that case. It’ll have to rely on the TLS-SNI-01 challenge, which uses port 443.

It worked as well.

Excellent!

We love seeing all sorts of how-tos and articles for however people use Caddy. Post it here in these forums when it’s done!
