Hi All,

Instance was created successfully no errors, but when I access instance via horizon console get error "operation timed out" in Chrome and IE. I am able to ping and ssh to instance on floating public ip.

I have 2 controllers, and to HA Proxy's

HAproxy 10.1.0.3 10.1.0.4 VIP 10.1.0.2

Controller: 10.1.0.5 10.1.0.6

Only error I see is apache2 log:

Looks like the VNC console is set to be at http://10.1.0.2:6080 , maybe make sure the IP is accessible from your machine (the one with the browser open, not the Horizon server) and that port 6080 is open on the controller? Can you access the console when you paste in the URL given from "nova get-vnc-console novnc" command directly into the browser?

That IP is the private VIP on the HA proxy. It is not accessible from my browser computer IP. Port 6080 is open on controller.

I thought that was for compute and controller to communicate on?

Update URL to public IP still getting error : Not Found The requested URL /130.245.183.133:6080/vnc_auto.html was not found on this server.

You probably want to make sure the novnc base URL on port 6080 is a public URL.

Horizon requests the novnc URL and token using nova get-vnc-console novnc. From the logs you posted, the URL is returned as http://10.1.0.2:6080/vnc_auto.html?token=97a6fa8a-58b0-42c2-81f5-07c025889fe2 in this case. This needs to be accessible from the places you want to access the console from, so I would say the baseurl config parameter shouldn't use a private IP.

Will try it and let you guys know, that definitely sounds like the issue.

Looks like the VNC URL is getting truncated, you need to include the http:// (or https, if you set up novnc with SSL) part of the URL in the nova.conf, e.g. in my env it looks like this: novncproxy_base_url = http://192.168.100.189:6080/vnc_auto.html

Config is correct has the http. Tried URL directly with out console. getting: Failed to connect to server (code: 1006)

Ok, at least now the console is loading! There's a lot of different possible reasons for that error message, I believe there's several questions about it on this website too. Sadly I'm not familiar enough with NoVNC itself to be much help with debugging. Good luck!
