Intermittent issue :Cannot communicate with the browser, please check the UiPath extension

Hi Folks,

I am facing issue in production robots, when the process involving chrome browser automation is triggered the bot faults due to “Cannot communicate with the browser, please check the UiPath extension.” initially even if it is in 3 retry and while rerunning manually it works. And when we check the Chrome extension is enabled and chrome native.exe will also be running.

We tried installing chrome beta version also which didnt work.
Kindly suggest any chrome configuration setting or bot configurations to avoid this.

Thanks in advance.

I will suggest to work with your IT department, usually on secure environments chrome is managed and is likely to disable the extension from time to time. I experienced that constant issue until they applied specific policies to allow the extension, I’m afraid every environment is different and different policies may cause issues.

Hi! Welcome to community,

Could you please upgrade the packages

And also reinstall the extension

Close all the browser and try to re install the Extension, It should work :slight_smile:

Hey Edwin,

Thanks for your response. The issue of getting extension disabled was also seen and in this case the it wont run in manual retry run also. So after that this was resolved. But issue in only few initial runs intermittently is still seen.

Hi Thiru_nani,

We have already tried reinstalling extension, kindly provide any specific version of extension if we can try. And which is package you mentioned to upgrade and version?

Thanks.

Hello @ullasarva
Is this happened recently or from starting itself you are facing this issue?
If its working for the initial execution and the extension gets disabled frequentlu, then it would be better to check whether any softwares are restricting the extensions and disabling it. Softwares like ZScalar can do that.

Hi!

Many ppl are facing the same issue. got resolved for many try to upgrade these packages

This was started recently. And even this is not regular during the initial run only this is observed and once reran this will not be seen. Will the softwares like zee scalar make this issue inconsistently?

I see Ui.Automation.Activities is already in latest verion v20.10.6

If it’s not happening always then the chance for other software to restrict is less. Also as you mentioned this has recently started.

Is there any version update happened recently for the uipath or to the ui automation package?

Hi!

Try to downgrade the packages and try it again
