Connection being auto declined after password dialogue

Post by FabiRotterKrones »

Hey everyone,

our current situation.
We use ultra vnc version 1.3.8.1 and have it configured as a service.

On some machines after a certain time period ( can be days or weeks of vnc running ) we cannot connect to the machines anymore.
They are pingable, we can still connect via UltraVNC and get the query for password and if you type in the wrong password it will still decline you with the error for wrong password.
But when we type the correct password instead of connecting successfully a dialog will open with "manual disconnected / server closed connection".
On the system itself vnc is still running as service.
A reboot will fix this issue and we can successfully connect to the machines again.
Anybody had this issue previously?

We see this occasionally, too. Does anyone have a fix?
