Proxmox not listening on default port

[droidus]

I am trying to access my GUI via https://<ip>:8007. Here is what my netstat looks like:

How do I configure it to listen on port tcp 8007?

 

[Moayad]

is port 8007 open in your server?
check it using nmap tool:

nmap localhost -p 8007 -Pn -T5
systemctl status proxmox-backup-proxy.service

I don't have a solution, but I seem to have the same problem...

~ nmap localhost -p 8007 -Pn -T5
[...]
PORT     STATE  SERVICE
8007/tcp closed ajp12

~ systemctl status proxmox-backup-proxy

Maybe a mismatch with ipv4 / ipv6 use. Configured ipv6 and now trying by ipv4?

i found:

https://forum.proxmox.com/threads/web-interface-ipv6-only.44101/

Thanks. I saw that one and a few google hits with various suggestions to disable ipv6 altogether. Done all that and now there is no :::8007 at all (good) and the only error I can glean is this one after a systemctl restart proxmox-backup-proxy...

proxmox-backup-proxy[18500]: Error: Address family not supported by protocol (os error 97)

For the life of me I cannot determine where proxmox-backup-proxy is configured to use any port, ipv6 or ipv4. Anyone have clue how to configure proxmox-backup-proxy to run on 0.0.0.0:8007 ?

I went looking for some config file using strace and all I could find is the same output as above. Google searches indicate that the error could be because of a localhost vs 127.0.0.1 issue or perhaps access to ipv4 is via ipv6 and my local network does not support ipv6 at all. I can't use this PBS server unless I can get to the gui for an ID to add it to my other proxmox nodes so I will give it one more shot with a fresh install before moving on to other backup solutions.

write(2, "Error: ", 7Error: )                  = 7
write(2, "Address family not supported by "..., 40Address family not supported by protocol) = 40
write(2, " (os error ", 11 (os error )             = 11

This is now two people reporting this same problem without a solution. My enthusiasm for Proxmox in general is waning.

FWIW I did a fresh re-install and was able to use ipv4:8007 to get into the web interface, configure a datastore and backup a VM from a clustered PVE. My enthusiasm for Proxmox just went right back up again ;-)
