I’ve installed the VNC program on two new UR10e (year 2024) but it doesn’t work. after a a couple of minutes appears a pop up with “Timed out waiting for a response from the computer” written on it. i tried to reinstall the VNC on the cobot, try different version of polyscope but still not work. there is no problem with the net or the subnet and both robot could be pinged.
with other 4 robots (years 2022 and 2023) it works correctly.
You should check that VNC is running on the robot. Make an SSH connection to the robot and type “x11vnc”. This should also start VNC if it isn’t running already. 
To connect to the robot with SSH:
- Connect robot and computer to the same network as you’ve done already.
- Open PowerShell or CMD in Windows.
- Type “ssh root@[IP ADDRESS]”
- You should be promted for a password now, which is “easybot”.
now it works. thank you!
We have updated to Polyscope version 5.16.1, and now we are unable to connect via VNC viewer. After connecting the robot through SSH, there seems to be no “x11vnc” program available.
We’ve found that any time we update Polyscope, we have to reinstall the VNC.
We have a USB stick with the VNC software on it - set up by one of our IT people - which auto-installs when we insert the USB stick.
Stick it in, wait about 30 seconds for it to install, then reboot the controller.
