SOLVED: No servers have been found

[fliberdygibits]

Just rebuilt my server after more than a year and I'm having a hard time with one thing.  When I visit page I get the screen "No servers have been found using the automatic server discovery." with a button to add server.  I've seen a lot of comments to clear browsing cache/cookies but I've not only done that but I've tried other browsers (opera and brave) and I've tried a private browsing tab all with the same results.

This is running in a proxmox VM behind NPM and it does the same thing via the URL on the public internet OR via the IP address here locally.

What server version are you running? 

Try disabling IPV6 in the network.xml config file:
<EnableIPv4>true</EnableIPv4>
<EnableIPv6>false</EnableIPv6>

Apologies, I'm doing this while making curry and was a bit sparse with information. Running 10.9.6 in an ubuntu 22.04 vm.

Also ipv6 was never enabled.... but per some other posts I enabled it then disabled it again to no effect.

Figured it out. In proxmox VM > Hardware > Network Device > Firewall=off. Turning off the firewall IN the VM and in the proxmox VM settings to the left isn't enough.

Is that really a "solution" though? Ports 8096/TCP, 1900/UDP, and 7359/UDP need to be open. Turning off the entire firewall is much less than ideal.

[fliberdygibits]

I have other firewalls in place that allow for those ports. I did not realize that Proxmox snuck this firewall in. Now that I've confirmed it was the cause of my issue I plan to loop back around and evaluate whether I'd like to make use of it. I didn't mean to imply I just blindly shut it off and walked away. For now the whole thing (JF, NPM, Proxmox) is all shut back down until I get time this evening to tinker with it.
