I’m on 6.6 and noticed today the VNC console in Sunstone is not working. When I click on the VNC button, I get two notifications:
VM startguac_action: 152 >> vnc
It appears there was a server exception. Please check server's log.
I looked everywhere in
/var/log/one/ and couldn’t find anything other than a 500 for this request:
[17/Jun/2023:08:31:51 +0000] "POST /vm/152/guac/vnc HTTP/1.1" 500 - 0.3126
Any hint on how to troubleshoot this would be appreciated, thanks!
As a workaround, I have commented out the following two lines
Which brings me back to the pre-Guacamole VNC experience.
EDIT: Another thing which might be relevant - Guacamole works no issues in Fireedge. So looks like the 500 is triggered before I’m even forwarded there.
I have removed all custom config and the issue still shows - at this point I think we should consider it a bug and have raised Guacamole VNC Throws 500 in Sunstone · Issue #6244 · OpenNebula/one · GitHub.
Will move discussion there.
