Title:
Remmina actively refusing VNC connection Ubuntu 22.04
Status in remmina package in Ubuntu:
Confirmed
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

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.
