Error executing MouseClick - Cannot forward the request Connection Reset

Hi Community,

My colleagues and I are having a very odd issue which a simple Mouse Click doesn’t work. We get this “Cannot forward the request” error. I have this example which the script should switch to the Windows calculator window and then click on number 8 and it fails:

Error executing MouseClickAction

We’re using RPA Express 2.2.

Another problem is that as soon as this happens, the Bot Manager looses the connection with the robot and we need to restart it to avoid “Unable to connect with the Robot” error (every single time).

I appreciate any help!
