Bug Description

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
CPU: AMD Ryzen 3 2200U with Radeon Vega Mobile Gfx (4) @ 2.500GHz

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.
