After 6.12.3 upgrade console fails to connect to VM

[malebron]

I just upgraded to 6.12.3 from 6.11.5

 

My Ubuntu 22.04.2 VM is started but the VM console (noVNC) will not connect ("Failed to connect to server")

 

This has "just worked" for so long, I'm not sure how to start troubleshooting this.

 

Any tips please?

Update:

I tried starting some other, previously working VMs - same console problem: "Failed to connect to server".

Then I tried a different browser (Chrome) - voila! It worked.

 

It seems after the Unraid 6.12 upgrade the VM console (noVMC) will no longer work with Firefox. (v115.02 at time of testing)

Did you try clearing the cache in Firefox?   Not unusual for this to be required after an upgrade to get noVNC working.

Thanks for the tip, itimpi. Unfortunately clearing the cache and restarting Firefox did not fix the problem.

 

It works like a champ in Chrome and Safari.

 

I should have mentioned I'm running the browsers on a Mac - OSX 12.5.1

I am here more than 6 months later for the same reason.  No joy with noVNC in Firefox.  Still works great in Chrome and Microsoft Edge.
