My management node was configured with FQDN/static IP and all other network settings correct and have tried to access the web interface but cannot access from two other (tried so far) Windows 10 systems on same network (using either Firefox / Chrome / Internet Explorer and Edge).

Using 'curl' from other Linux (Ubuntu or Debian) systems on the network show the web interface is there and I can access the proxmox web interface from a Ubuntu system / Firefox on same network no issues (accepting the security cert).

Interestingly using 'nmap' from the same Ubuntu system as above does not show port 8006 as open but I can access the web interface from curl and Firefox as I mentioned.

Pinging the proxmox node works fine from all other systems (Windows and Linux).

I used https://{IP ADDRESS}:8006/ in all cases to try to access the proxmox web interface.

I'm not sure if it's something on my network somehow handling Window and Linux traffic/ports differently or the other thing I've seen mentioned is a potential issue related to IPv6... I didn't mess around with any of that just followed the default proxmox install procedure. Any ideas? Thanks!
