Problem with External component exception

Help Studio
1

Hello,

I’m experiencing a problem with one of the robots I’m currently testing.
I have been running on test machine for 3 weeks and it was fine and suddenly is stopped working.
It has been throwing a couple of different errors, currently it fails at activity that query Access DB.

This is full stack of error, but I can’t figure it out from it what exactly is wrong, what is causing exception. Can anybody tell me what can cause this kind of exception ?
On my dev computer, it works fine.

  • Info: External component has thrown an exception.

RemoteException wrapping System.Runtime.InteropServices.SEHException: External component has thrown an exception.

I’m not 100% sure but it looks like robot can’t connect to DB.

Thanks @Pablito, I’ve found out that there is a network problem on test machine.
