Tutorials and FAQs / Re: Tutorial: Caddy (Reverse Proxy) + Let's Encrypt Certificates + Dynamic DNS

I ran the curl command a few more ways and got some results that seem mildly interesting. Figured I'd repost them in case they're telling to you...

Code: [Select]

* Connection #0 to host www.mydomain.us left intact

So it looks like a request to the bare domain responds over http/port 80, a bare request trying to force https results in a TLS handshake error, but a https request to www works.  That's particularly interesting to me since I didn't set up a www entry in my DNS record.

Is there anything noteworthy you're seeing from those results?

I'm running through the troubleshooting steps and reviewing firewall rules etc to see if I can find something on the firewall end that's stopping the request from passing through to the client...

Apparently my brain isn't turned on yet today. I didn't even notice that both tests were for port 80. Here's 443

Code: [Select]

curl -v sonarr.example.us:443
* Host sonarr.example.us:443 was resolved.
* IPv6: (none)
* IPv4: <wanip>
*   Trying <wanip>:443...
* Connected to sonarr.example.us (<wanip>) port 443
> GET / HTTP/1.1
> Host: sonarr.example.us:443
> User-Agent: curl/8.9.1
> Accept: */*
>
* Request completely sent off
* HTTP 1.0, assume close after body
< HTTP/1.0 400 Bad Request
<
Client sent an HTTP request to an HTTPS server.
* shutting down connection #0

Looks the same as what I got on port 80, other than the "HTTP/1.1 308 Permanent Redirect" line. So if cloudflare is getting through to Caddy, any suggestions as far as what's blocking the request from getting through the firewall?

As for setting up cloudflare, assuming my current issues are on the firewall side, there's nothing special about the setup. You just have to create an A record for your root domain, or using * to get a wildcard cert. I didn't even create the DNS entries for my subdomains, cloudflare did it dynamically.

I think you have to configure "trusted proxies" to a list of cloudflare IPs in General Settings. (if you use it as CDN and not only as DNS provider)

There can also be cloudflare specific settings to be done at cloudflare itself I do not know about. I dont use it sorry. I think Cloudflare can itself be tje reverse proxy entry point for domains configured on it.

Check out what

curl -v example.com

returns from the outside.

I'm only using cloudflare for DNS to access my home network. My server is inside the network. As far as cloudflare specific settings, to my knowledge there aren't any. I watched several youtube tutorials on setting up cloudflare as DDNS with OPNSense, but unfortunately, I couldn't find anything tied to your plugin (there's really next to no info I've found outside of this thread and a handful of posts you've replied to on Reddit)


Here's the result of the curl entry...

Code: [Select]

I'm working on getting Caddy set up on my OPNSense box, and running into some issues that are probably stupid user error from someone who's brand new to the featureset of OPNSense. Hoping someone can help.

My situation: I got Caddy set up with cloudflare pointing to my domain. Was able to obtain a wildcart cert from cloudflare. Set up my subdomains for Plex, Sonarr, HomeAssistant, and router GUI.

I'm getting 502 errors on all of them from the WAN, but can access Plex from the local network (the rest give 502). I can't play anything on Plex, but can see and interact with my dashboard.

As far as my setup goes, here's what I have:

Cloudflare DNS records:

Code: [Select]

ha.example.us. 1 IN A <my WAN IP>
plex.example.us. 1 IN A <my WAN IP>
*.example.us. 1 IN A <my WAN IP>
example.us. 1 IN A <my WAN IP>
router.example.us. 1 IN A <my WAN IP>
sonarr.example.us. 1 IN A <my WAN IP>
I set up the firewall rules as directed in the tutorial, with HTTP and HTTPS rules on both LAN and WAN.

Domain:

Code: [Select]

Protocol: https://
domain: *.example.us
Cert: ACME
DNS-01 Challenge: checked
Dynamic DNS: unchecked
Subdomains:

Code: [Select]

Domain: *.example.us
Subdomain: plex.example.us
Dynamic DNS: checked
Other services are set up the same.

HTTP Handlers:

Code: [Select]

Domain: *.example.us
Subdomain: plex.example.us
directive: reverse_proxy
Protocol: Https://
Upstream Domain: plex server's local IP
Upstream Port: 32400
TLS Insecure Skip Verify: checked
Other services are set up the same, but with correct subdomain, local IP, and port.


Here's a my caddyfile:

Code: [Select]

Any help here? Do I need to do any setup on my Plex/Sonarr/HA box? Forward ports 443/80? Is unbound DNS tripping me up somehow? Or did I just miss something else?
