listening mode stopped working after update to 1.7.1.0 x64

Post by nagysifa »

Hi!

First of all thank you for developing this essential networking tool!

I have been using listening mode (UltraVNC reverse connection) for many months with version 1.6.4.0 on my server with command from a batch file:

START "" "C:\Program Files\UltraVNC\vncviewer.exe" -listen 55500

after updating to 1.7.1.0 the clients can no longer connect... (the firewall/router connections are not changed)

After reverting to 1.6.4.0 version everything works again...

These window appear instead of the remote desktop:

Thanks for any help or suggestion!

Thanks for the feedback!

1.7.1 is still alpha, only use for internal testing.

Was viewer and server replaced or only the viewer?

This limit the bug chase.

I installed the file (UltraVNC_1710_x64_Setup.exe) to my server
Started the listening mode (as always): START "" "C:\Program Files\UltraVNC\vncviewer.exe" -listen 55500

unfortunately it still do not work:

I tried it with 1.6.4.0 and 1.7.1.0 on the client side...

Can't repeat it.
START "" "C:\Users\XXX\Desktop\git_ultravnc\vncviewer\Debug\vncviewer.exe" -listen 55500
this show the viewer on the systray, and i can proper connect:

Possible it's related to save config settings.

When do you get the dialog, on start or when the server connect?

see config and rename the options or other config files to test:

I get the error window after I initiate the connection on the remote client...
I will try your suggestion and get back to you.

I have the same problem.
It occurs when the connection starts.

Could You point me, where are the settings changed in "UltraVNC Server - Settings" saved ?
It used to be saved in "C:\Program Files\UltraVNC\ultravnc.ini" file - ( for my setup ) but now I can not find the file ...

It is not in the installation folder, in the ProgramData, in User folder or in the registry ... what am I missing ?

Thank You!
