<![CDATA[XOA Console not coming up]]>Hi,

Background
My XCP Ng was working all fine, when I decided to change my broadband provider and the troubles started. The main CIDR range changed from 192.168.1.x to 192.168.0.x
and as I have my server hosted under an extended router which was still in the old CIDR range (and hence not working). DHCP fixed, and all working.

Problem
Not sure if this is related or not, or may be a coincidence, but now, the "Console" tab is empty - except the icons & graphs - i.e. (vnc) console doesnt come up, which means I cannot launch a new VM - as after launching I cannot install the OS and proceed to SSH.

I have tried from the last 3 days without luck. My errors on browser console on "VM > console" tab keep repeating -

Failed when connecting: Failed to connect to server ( (code: 1005)) util.js:44:54
Tried changing state of a disconnected RFB object util.js:44:54
WebSocket on-close event util.js:42:54

Removing XOA issues from equation
As for XOA, other than the default install, I have now downloaded / compiled XOA on a different VM hosted on same XCP Ng - and the same problem persists i.e. Console is not shown

Ask
So starting from scratch upwards, could the experts pls explain the assumptions that XOA makes on the XCP Ng box to show a VM's console?
What can I check, what needs to be fixed?

Thank you !

Tried this -

XCPNG | ~/_scripts > netstat -tulpn | sed -n '1,2p;/5900\|80/p'

VNC on the XCPNg box is listening to 127.0.01 : 5900, may be - I should change this to listen to 0.0.0.0 ?

Also, something to do with protocol used - the browser > inspect > network - seems to use ws:// protocol and receives a 101 - upgrade, should it have been vnc ? ( apologies if its a random guess rant here) -- Attached screenshot of browser console logs.

FYI - 192.168.0.49:3000 - is where my XOA VM is running as a VM on XCP Ng (192.168.0.45)
and the logs below is when the console for itself (i.e. same IP)

You might have a discrepancy between the IP you use to connect and the internal IP reported by XCP-ng, so likely your XO is trying to connect the console via a different IP (the old ones?)
