My configuration,
I start 10 jobs by on trigger => Another job is triggered for each 2 new item(s)
I have 3 VM with 5 sessions.
I’m using only 5 differents userid in each Vm.
The extention for edge is already install in each Session.
We face this issue randomly when the 10 performers start in the same time.
We create 3 days ago, one different folder by edge profile used by each user profiles (c:/Uipath/{{userid}}) I copy/past all the file from edge/DataUser in each folder. no issue Durring 2 days but I faced the issue again this morning.

Version: 2020.10.2
extention : UiPath Web Automation Version9.0.6824

Any idea regarding the source cause?

Thank you for your help

Please go into “File → Tools” and allow the edge extension, this shall then allow the browser communication

Hi @jubourel

Any news on that issue ?
Experiencing the same problem right now with UiPath randomly not communicating with Edge when launching a new session.

Tried to surround the Open Browser activity with a Retry Scope but still, UiPath was not able to communicate with Edge for more than 20 minutes.
