Bug #23977
RealVNC Viewer can't connect to VM VNC with auto quality enabled
Description
If you attempt to connect to the VM VNC port with RealVNC VNC Viewer you will get and error
"RFB protocol error: invalid message type 152"
If you then reconfigure the connection to use High Quality instead of Auto, it will connect correctly.
I'm guessing the VNC server doesn't support/understand the auto quality setting.
Tested on Mac OS X 10.11.6 with VNC® Viewer 6.1.0 (r27437) x64 (Apr 26 2017 11:04:58)

Updated by Marcelo Araujo - Status changed from Unscreened to Screened
- Priority changed from No priority to Nice to have
- Target version set to 11.0-U1
I bet that it is a screen resolution problem, by default we used to use 1024x768 but recently I added a new option where you can set the screen resolution for the VNC Device. This option would not land on RELEASE, it will be available only on Nightlies.
You can see more info here: https://bugs.freenas.org/issues/23894
I will keep this ticket open, I will test it to make sure it works.
Thank you!

Yeah, that was me.
Switching to high quality in RealVNC's VNC Viewer solved the problem immediately. I was able to view the vnc on both mobile and PC. Highly recommend a note be added somewhere in the VM GUI, or at least in the documentation.

Great guys for all the report.
I didn't have enough time to debug this issue, I'm still wondering if there is any problem with screen resolution.
But this bug is a nice one to debug. I will keep you two updated with my progress as soon as I start to work on it.
Thanks again,

- Target version changed from 11.0-U1 to 11.2-BETA1
We might change to libvncserver that is something I'm working on. So, could not find yet the main reason of this problem.
I'm moving this issue targeting to 11.2.

Thanks again,
Just wanted to confirm setting quality to high in the client worked or me as well. Luckily this was the second result from Google. Thanks for what you do!

Nice to know there is an easy workaround, but it would be nice if it just worked. Still in FreeNAS-11.0-U2 (e417d8aa5).

There is a new lib for VNC that I want to integrate on FreeNAS at least on its version 11.2-RELEASE that will solve this problem.
