Created attachment 1759268 [details] Perfectly good fqdn in the system fails check in the UI Description of problem: When attempting to deploy HC Gluster via Cockpit, the FQDN check fails, despite the FQDNs being fully resolvable forward and backward and the internal network to be completely routable. Getting "FQDN is not reachable" This is similar as in 1679540. Version-Release number of selected component (if applicable):cockpit-ovirt-dashboard-0.14.17-1.el8.noarch from ISO: ovirt-node-ng-installer-4.4.4-2021020810.el8.iso How reproducible: 100% Steps to Reproduce: 1. Deploy ovirt-node-ng-installer in compatible hardware, 3 hosts 2. via external IP get to Cockpit 3. Start installation process using a FQDN from internal ( as suggested by dialog box) for data network, we use a VLAN only for data traffic. Actual results: "FQDN is not reachable" Expected results: being able to install HC oVIrt/Gluster in 3 nodes.

While I agree that fqdns must be correct, the check is not done in the correct context and would only work if the client machine is connecting directly to one of the internal IPs that is going to be used to deploy as.
Created attachment 1759337 [details] Exerpt from logs and tests I think I can help to make the fqdn, ip, and interface detection more robust. Write to me if you would like me to lend a hand.

Write to me if you would like me to lend a hand. Hey Guillem! Have you added the ssh-ids to the machine running cockpit-ovirt?
