VncViewer closes when I try to connect again

[drigoskalwalker]

I'm using wayvnc as vnc server in my Linux machine.
I'm using ultraVNC Viewer on my Windows 11 machine.

I'm able to connect succefull and everything works.
But if I close the connection (closing the window) and try to connect again
the viewer shows up a black screen and immediately closes.

When I use other viewers like RealVNC Viewer
I'm able to reconnect as many times I want

Using ultraVNC Viewer I have to restart my vnc server everytime I close the connection and need to connect again.

Version viewer, version wayvnc server ?
Did this also happen with a previous version of wayvnc ?
After you disconnect a realVNC viewer, can you connect with a UltraVNC viewer ?
After you disconnect a UltraVNC viewer can you connect with a realvnc viewer ?

Hi,
I tested WayVNC 0.8.0 and the master branch, same behavior.
I tested UltraVNC 1.5.0.0, 1.4.3.6 and 1.3.8.1
TigerVNC Viewer has the same behavior.

• Did this also happen with a previous version of wayvnc ? - YES.

• After you disconnect a realVNC viewer, can you connect with a UltraVNC viewer ? - NO.

• After you disconnect a UltraVNC viewer can you connect with a realvnc viewer ? - YES.

Looks to me that wayvnc is in a special status after a viewer disconnect to prevent viewers ( expect realvnc) to connect again.
As multiple flavors viewers has the same issue i'm expecting that they don't follow 100% rfb or use some subdialect that isn't backward compatible. I'm unable to debug what happen on the server site, making it hard todo the required changes.

If wayvnc can provide info on what need to be change we will implement it.

Please post this on https://github.com/any1/wayvnc/issues , as multiple viewers has the same issue.

I would post it myself but can't provide extra info if they ask question on setup and config.

I've never been able to reproduce this myself.
