Proxmox is configured to use it's default self-signed SSL certificates.

Here is the config on NPM:

{
"id": 7,
"created_on": "2021-07-18T01:57:08.000Z",
"modified_on": "2021-07-18T02:11:33.000Z",
"owner_user_id": 1,
"domain_names": [
"proxmox.mydomain.net"
],
"forward_host": "192.168.1.103",
"forward_port": 8006,
"access_list_id": 1,
"certificate_id": 1,
"ssl_forced": true,
"caching_enabled": false,
"block_exploits": false,
"advanced_config": "",
"meta": {
"letsencrypt_agree": false,
"dns_challenge": false
},
"allow_websocket_upgrade": true,
"http2_support": false,
"forward_scheme": "https",
"enabled": 1,
"locations": [],
"hsts_enabled": false,
"hsts_subdomains": false
}

Connecting directly to the IP/port via https works (get a cert warning as expected with self-signed cert on Proxmox). When I connect via the NPM configured URL I get the ERR_CONNECTION_REFUSED. Do I need some custom config to get this working? Does NPM support self-signed certificates on the proxy host?

Thank you

I did something dumb. I had DNS pointing to my Proxmox host not NPM.
