Public bug reported:
Recently installed the developer version of Ubuntu 22.04 on my laptop
with the following specifications.
Lenovo-ideapad-330-15ARR
------------------------------------------------------
OS: Ubuntu Jammy Jellyfish (development branch) x86_64
Host: 81D2 Lenovo ideapad 330-15ARR
Kernel: 5.15.0-22-generic
Uptime: 1 hour, 5 mins

Shell: bash 5.1.16
Resolution: 1366x768
Terminal: /dev/pts/0

org.remmina.Remmina - SNAP Build - 1.4.25 (git v1.4.25)
Desktop Environment: GNOME
Connecting to: Ubuntu Jammy Jellyfish (development branch) x86_64
Connecting via: VNC
Description: After installing Ubuntu Jammy Jellyfish (development
branch) x86_64 I tested the VNC connections that I have set up for my
machines. My laptop is able to connect to any system with Ubuntu
20.04.4 LTS installed on it. However, when trying to use Remmina to VNC
into my laptop with Jammy Jellyfish installed from another machine with
Ubuntu 20.04.4 LTS installed the connection is actively refused.
I have already checked to make sure that all sharing features are turned
on along with the UFW firewall configured to allow connections through
port 5900. Also uninstalled Remmina, and reinstalled it on my laptop
with Jammy Jellyfish installed. Still get the same issue. The exact
error message that comes in in Remmina is "Unable to connect to VNC
server" when everything is configured correctly on my laptop with Jammy
Jellyfish installed.
Just for the sake of experimentation, I set up Jammy Jellyfish on
another machine of mine to troubleshoot the issue further. When trying
to connect from one machine with Jammy Jellyfish installed on it to
another machine with Jammy Jellyfish installed on it;I still get the
same error "Unable to connect to VNC server" within the Remmina
software.
In summary, any machine of mine with Jammy Jellyfish is able to VNC into
any machine with Ubuntu 20.04.4 LTS installed on it. No machine with
20.04.4 LTS is able to VNC into another machine with Jammy Jellyfish
installed. VNC connections in Remmina between machines with Jammy
Jellyfish installed are unable to connect to each other.
