Connects then disconnects right away

[zyahko]

I just recently trying upgrading the computers in my network from UltraVNC 1.0.8.2 to 1.2.0.1 and some of them work fine but others that we use to connect over a VPN have been connecting after password is entered and then it acts like it is about to connect but then just disconnects and closes the UltraVNC window.

I did install this version by using a patch management software to deploy the needed files and ran a batch file to silently install the UltraVNC after also using a batch file to run the uninstall executable that was found within the UltraVNC folder.

Any clue why it would act like is connects but then disconnect right away?

Does server and viewer have the same version?

Also just to let you know I downgraded the computers that I mainly use viewer on to 1.0.8.2 and it connects fine now with the server 1.2.0.1

Interesting. I have the same issue using version 1.2.1.

I also have the same problem on viewer 1.2.1.6
It connects, accepts the password and then gives error:
Server closed connection
-Manual closed
-Network disconn

This sites connection worked fine for some time, now does not work.
As far as I know there were no firewalls or changes etc.
It did it on a previous version, so I upgraded to 1.2.1.6, but it is still the same.
