Proxmox Self Signed Certificate Subject Alternative Name

[azaralizain]

Hi there.

I have spent hours trying to search for how to add new entries for the Subject Alternative Name (SAN) in Proxmox's Self Signed certificates, but just being unable to find a clue.

So far, I have added it in the hostname and hosts file, reissued the certificates and restarted the proxmox node, but nothing happens.

Will appreciate any and every help possible!

Not really tested it myself (nor did I have to because I'm using an official certificate myself), but just a thought:
It looks like it grabs all the IP's it is using itself, and the DNS-records it finds for those IPs (the PTR-records)
So you should only need to add alternative names for your lan-IP, or (probably more cleanly too) add a bridge with it's own IP (does not have to be reachable, just exists I would think) and add that IP and the name(s) you want to the hostsfile, reboot the server and re-issue the cert.

Or just get a letsencrypt or a bought certificate with the name(s) that you want.
