I'm encountering this problem after a fresh install of Mirantis Fuel 9.0 and then immediately upgrading to 9.2 (didn't even login to the Fuel web interface prior to the upgrade).<br>
<br>
I've verified that nailgund is running and the network configured in 'fuelmenu' during the initial 9.0 install is legit with Internet connectivity (<a href="http://172.16.0.0/22" rel="noreferrer" target="_blank">172.16.0.0/22</a> network, 172.16.3.250 is fuel server, 172.16.0.1 is the Internet gateway and 172.16.1.1-172.16.2.254 is handed out via the fuel DHCP server). I've also verified that no other DHCP servers exist on this network, no errors or warnings in the 'fuelmenu' portion of the installation.<br>
<br>
I've installed this before using the same exact methods/options on some Dell hardware in a lab of mine however I'm having this problem on a production deployment using some older HP servers. The only difference between the functional installation and this one is the IP ranges that were used and I set a root/admin password on the production setup (I left admin/root at default on the functional setup). I have a suspicion that using the <a href="http://172.16.0.0/22" rel="noreferrer" target="_blank">172.16.0.0/22</a> network as the admin/PXE network for fuel deployments might be the culprit as I noticed that the nailgund config file defines '<a href="http://172.16.0.0/16" rel="noreferrer" target="_blank">172.16.0.0/16</a>' as 'PUBLIC' in the template section as shown below:<br>

I tried using Mirantis Fuel 9.0 without patching and it doesn't exhibit this same problem although this time around I left the admin/root passwords at default and did not set them as I did with the previous installations when I upgraded directly to 9.2 so I'm not sure if that is factoring in here.<br>
<br>
Any ideas what the issue may be?<br>
<br>
Also, sorry if this is a repost, I sent this email many hours ago and didn't see it appear on the mailing list archives, not sure what the issue is or if I didn't wait long enough.<br>
