Uipath- how to resolve UIpath cannot communicate with browser IE


I have an issue with open browser activity, when trying to open an url with open browser activity, robot fails to launch the url and it fails with exception“UIpath cannot communicate with Browsr IE.”

I have the latest enterprise version of UIPath 2020.4.1 and IE11 version. It is working very inconsistenly, sometimes robot launches the same url without any issues and sometimes it fails with exception “ UIpath cannot communicate with browser IE”.

Any help in fixing the issue is very much appreciated!

Thanks in advance.

Hi @VamsiGaliveeti

So for handling this situation use retry scope activity and within retry scope use open browser steps what u r performing.

So if you get any issue while opening the browser then it will retry for the max count you provide

Mark as solution and like it if this helps you :slight_smile:

Hi Pratik,

We have tried that approach as well but no luck :frowning:

Hi @VamsiGaliveeti
See if this helps with your issue: https://docs.uipath.com/studio/docs/enhanced-protected-mode-in-internet-explorer

Hi Matthew

Protected mode is disabled in browser.we are facing the issue with browser inconsistently, sometimes it runs and sometimes it fails with Uipath cannot communicate with IE browser.

Please help me with that specific exception.

Do you have issues with launching the browser or with activities within open browser?

Otherwise start explorer as a process (Acitvity: Start Process) : “C:\Program Files\Internet Explorer\iexplore.exe”

edit: after that you can use the Attach browser.
See if that works for you.


I have an issue with open browser activity while trying a launch a new session with the urls.

I am using parallel foreach activity which opens 20 open browsers with different urls using parallel for each activity.
