Hi, I’m experiencing this error. I’m using Studio 2018.1.1.

It runs smoothly when run/played in robot tray but in orchestrator schedule, it’s failing.

Execution error : UiPath.Core.BrowserOperationException: Cannot communicate with the browser, please check the UiPath extension.

Need immediate advise please…

Thanks,
Gerlie

Can you remote the machine using the same user as robot and open browser? If there is a pop up coming up it will give that error

Hi Gabriel,

Yes, i can. Actually, as of the moment, the issue was resolved. I am not sure what resolved it. I did a lot of setup before that didn’t work. Specifically, I removed UiPath extension from Chrome and reinstall, enabled access from incognito and allowed access to file. Wasn’t working, I even renewed license of my community edition of UiPath Studio, restarted both Studio and Ui Robot. But the last thing I did was restarted the Windows VPS where it is installed and it worked perfectly.

Thanks for the response,
Gerlie

Install Chrome 32 bit version, it should working fine.

Entra a la configuracion de la extension y verifica que este activada la opcion “Allow access to file URLs”
