After Upgrade to 22.04 unable to access remote desktop via VNC legacy (was working on 20.04)

I was able to use vncviewer in the past to this machine with no problems. After the upgrade I configured teh Remote Desktop Sharing correctly in the Settings. When I try to connect to the machine I get:

vncviewer 192.168.20.19
Connected to RFB server, using protocol version 3.8
Performing standard VNC authentication
Password: 
Authentication successful

But no screen. Apparently everything is working, but I get no screen back to the machine that is using the vncviewer. Tried everything that I could find /think of:

X11, Wayland, rdp, vnc, no firewall, ...

If I stop the remote with:

systemctl --user stop gnome-remote-desktop.service

I get:

vncviewer 192.168.20.19
Connected to RFB server, using protocol version 3.8
Performing standard VNC authentication
Password: 
Authentication successful
vncviewer: read: Connection reset by peer

BTW, the above connections were made in loopback (the vncviewer is being executed in the 192.168.20.19 machine).

I need to use "barrier" to this machine and so RDP is out of the question, although I've used it to try and debug the situation, but I get the same behaviour: connects but no display back.

I have another 22.04 machine that was upgraded and the VNC is working fine.

So, at this moment I'«m completely at a loss. Any help is appreciated, namely to try and debug why this is happening on this machine.

Thanks.

Yep. I am. When I connect I used the Ubuntu over X. Even already tried with the WaylandEnable=false on /etc/gdm3/custom.cof

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
