Cannot communicate with the browser in incognito mode - Chrome | Cloud Robots

Help Cloud Robots

Hello there!

I’m making a RPA Automation workflow in Studio, that works well on the debug versión, but once I publish it and run in on the orchestrator, it fails by throwing the Cannot communicate with the browser, please check the UiPath extension..

We are using an Automation Cloud Robots VM, with the base image with supported browsers. The workflows tries to use an private session in chrome, because for some reason, the VM stores the cache of the site we are automating.

I’ve tried activating the extension in incognito mode, reinstalling the extension through Studio, changing the robot advanced settings, but nothing works.

Thanks in advance

Did you turn on incognito mode in the extension?

Hi, @fsantander Welcome to Community!

check that the ChromeNativeMessaging.exe process is running and not blocked by antivirus on the VM. Also, increase the open Browser activity timeout and enable the retry option in project settings to handle extension initialization delays.
If issuees persist try reinstalling the chrome extension and clear the browser cache to prevent corruption from cached data affecting communication. Restart the VM after these steps for full effect.

Hi @fsantander

When you login to your VM, are you able to see the extension installed and enabled in chrome there?

Hello @fsantander

When you say that the extension is installed and activated for incognito - have you done it on the specified VM and with the specified robot account?

Hi @fsantander

Are you able to login to the VM, then kick start the process from orchestrator and see the process in action?

We might be able to find out the missing part.
