HAProxy proxies hosts unreachable
-
@digimd said in HAProxy proxies hosts unreachable:
No wan ports opened.
This would be necessary for ACME to work, I think.
The rest are "unreachable".
No error page from HAproxy?
This would let me think, that it isn't listening on the requested port.Is HAproxy listening on multiple IPs, one for each backend, or a single IP?
How did you configure it? -
@viragomann ACME works fine through Cloudflare DNS challenge. I followed Tom Lawrence videos to set this up. HAProxy stats tab shows all backend as Green; hence available. I am listening on my managent vlan where I also have my pfsense interface listening on. I am using 443 as the listening port. Happy to share screen shots if needed.
I am not sure what I am missing.

@digimd
So you have a single frontend or one primary + shared ones and HAproxy has to distinguish, how to forward. How is this done?
Via SNI? This would only work for https.Otherwise post the config from the bottom of the HAproxy general settings.

@digimd
You have only one frontend, which is listening on port 443.
Maybe I'm not clear, what you intend. Accessing the same hosts with and without SSL? Or redirecting non-SSL to SSL? -
@viragomann I have one frontend that handles the ACLs. I am accessing backends with https with unsigned cert and one http. They belong to different services. I intend to access my self-hosted services with proper ssl without opening a WAN port.
-
@digimd
And which host is not accessible? -
@viragomann all are unreachable except for router which points to my pfsense.
-
@digimd
Try to remove the checks at
"Add ACL for certificate CommonName"
"Add ACL for certificate Subject Alternative Names"
in the frontend settings.For testing the connection you can also state a default backend and see if you can access it.
If this works, the rules are not applied. -
@viragomann I removed the checks when present and it made no difference. I sat a default backend other than router, and no change either.
I am considering to move to self hosted reverse proxy and get done.

@digimd
You said, you get just a time out, when you try to access a page.
If the request hits HAproxy it will give any respond, however. So I suspect, that there is something else wrong.Ensure that the host name resolves properly to the IP, which HAproxy is listening on.
-
@viragomann I am not sure what type of error. Essentially page is unreachable, without error code. I am remoting now through tailscale on pfsense and I get this which is likely a dns or firewall rule.
ERR_CONNECTION_REFUSEDI changed listening IPs to 0.0.0.0:443 and no change. Could this be a firewall rule issue?!
-
@digimd
It could maybe a reject rule, giving this error. However, do you have any?If I got you correct, you want to access the sites only from inside the network?
-
@viragomann Yes, I meant to keep all ssl access local. I have the listening interfaces allowed to access all target destinations. I am just throwing the idea although I don't think it's the issue. Thank you for following through.
