Hello everyone, seems to be lots of info on this topic, but we are unable to use VNC when going through an Apache proxy. VNC works as expected if accessed directly from OpenNebula/Sunstone, and we are able to access and perform all other functions through the proxy, but when accessing VNC through proxy we get the " VNC Server disconnected (code: 1006)" so I assume it is related to websockets/ws\_tunnel? Here are the details: Ubuntu 16.04.3 OpenNebula 5.4 on single host (IP 192.168.1.71) Apache 2.4.18 with wstunnel enabled (IP 192.168.1.90) No firewalls between OpenNebula host and Apache host ss -ntap |grep 29876 LISTEN 0 100 \*:29876 _:_ SSL not used sunstone-server.conf :vnc\_proxy\_support\_wss: no Pretty sure this is where the issue is… just do not know how to resolve apache config: ProxyRequests off RewriteEngine on ProxyPreserveHost on ProxyPass / [http://192.168.1.71:9869/](http://192.168.1.71:9869/) ProxyPass / ws://192.168.1.71:9869/ apache log entry: “POST /vm/11/startvnc HTTP/1.1” 200 568 “[http://192.168.1.90/](http://192.168.1.90/)” “Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:56.0) Gecko/20100101 Firefox/56.0” firefox console: Firefox can’t establish a connection to the server at ws://192.168.1.90:29876/?token=blahblahblah - shouldn’t firefox try to connect to .71? I am open to using nginx, and have tried briefly with basically the same result. I’m sure it is a ‘ws’ directive issue, just not sure what. Thanks in advance. ---

Really could use some help, thoughts, suggestions, etc. I believe I have almost found the end of the internet looking for the solution… Thanks in advance. ---

So i believe the issue appears to be related to this: Firefox can’t establish a connection to the server at ws://192.168.1. **_90_** :29876/?token=blahblahblah The .90 is the proxy, not the sunstone server. Any ideas/thoughts on why it is trying to access the proxy rather than sunstone? ---

I was able to resolve this using traefik as the proxy and configuring an additional entrypoing, frontend, and backend for port 29876. this proxied the traffic from the client machine to sunstone when it tried to access port 29876 on the proxy. ---

Can you post your apache configuration here please?? I have an apache using mod\_proxy, i reverse in https the opennebula FE but when i try to open vm consoles under novnc or spice, nothing appear. ATM the apache server configuration reverse proxying OpennebulaFE is: \ ServerName localhost ProxyPreserveHost Off RewriteEngine on RewriteRule ^(.\*)+(nebula)$ %{REQUEST\_URI}/ [R=301,L] SSLEngine on SSLCertificateFile /etc/pki/certs/xxxx.crt SSLCertificateKeyFile /etc/pki/private/xxxxx.key SSLCertificateChainFile /etc/pki/certs/xxxxxxxx.pem \ ProxyPass [http://xx.xx.xx.xx:9869](http://xx.xx.xx.xx:9869) ProxyPassReverse [http://xx.xx.xx.xx:9869](http://xx.xx.xx.xx:9869) Many thanks Igor ---

Hi @mh_opennebula , I’m having the same issue setting up traefik v2 and sunstone/vnc. Can you please share your traefik configuration? I’ve tried different solutions but nothing worked. Thanks Jaime
