When adding domain name to caddyfile i lose connectivity

Help
1

1. The problem I’m having:

when i add my domain name (stream.sargtv.com) to the caddyfile replacing :80 i can no longer connect to the domain on any browser, curl localhost and curl stream.sargtv.com both return blank.

curl -vl stream.sargtv.com returns

 Connected to stream.sargtv.com (140.238.134.56) port 80 (#0)
> GET / HTTP/1.1
> Host: stream.sargtv.com
> User-Agent: curl/7.81.0
> Accept: */*
>
* Mark bundle as not supporting multiuse
< HTTP/1.1 308 Permanent Redirect
< Connection: close
< Location: https://stream.sargtv.com/
< Server: Caddy
< Date: Mon, 31 Jul 2023 03:17:29 GMT
< Content-Length: 0

removing the domain name brings me to caddy’s start page like normal. this all started after an attempted reverse proxy to localhost to run an owncast server.

2. Error messages and/or full log output:

4. How I installed and ran Caddy:

a. System environment:

Canonical-Ubuntu-22.04-2023.06.30-0 running on an oracle cloud vm

b. Command:

PASTE OVER THIS, BETWEEN THE ``` LINES.
Please use the preview pane to ensure it looks nice.

c. Service/unit/compose file:

d. My complete Caddy config:

{
        acme_ca https://acme-staging-v02.api.letsencrypt.org/directory
        debug
}

# 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.

stream.sargtv.com {
        # 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

Hi, thanks for filling out the template!

That is working correctly. Caddy is simply redirecting your client to use HTTPS instead of HTTP.

Try using curl -vL for your command and you should see content. If not, then there’s probably some sort of networking misconfiguration, like maybe your firewall doesn’t have port 443 open.

That would be consistent with this log message:

{
	"level": "error",
	"ts": 1690772461.3763316,
	"logger": "http.acme_client",
	"msg": "challenge failed",
	"identifier": "stream.sargtv.com",
	"challenge_type": "tls-alpn-01",
	"problem": {
		"type": "urn:ietf:params:acme:error:connection",
		"title": "",
		"detail": "140.238.134.56: Error getting validation data",
		"instance": "",
		"subproblems": []
	}
}

Caddy was still able to get a certificate using port 80, but you’ll need to make sure port 443 is open to your host.

do you know how i can do that on linux ubuntu? its odd to me that this was working before and just quit after an attempted reverse proxy.

Before you were only accessing it over port 80. Caddy’s default is 443 when you give it a domain name.

Sorry, but I’m not really sure how to help beyond that. I can help with Caddy stuff, but if you have a port blocked on your infrastructure, it might be on your system or it might be a firewall or some other network box, who knows. You’ll have to figure out why the port is blocked.

ok, i managed to fix this by adding port 443 into the iptables on ubuntu.

now my issue is that it was all working a few hours ago. i havent touched it and now its giving http error 502

That means your proxy backend/app isn’t responding.
