Hello

I'm trying to run Selenium tests with Azure DevOps and I'm getting this error message:

[Failed] [disconnected: Unable to receive message from renderer (failed to check if window was closed: disconnected: not connected to DevTools) (Session info: headless MicrosoftEdge=119.0.2151.72)] [Details at 1 below]
Exceptions:

1. disconnected: Unable to receive message from renderer (failed to check if window was closed: disconnected: not connected to DevTools) (Session info: headless MicrosoftEdge=119.0.2151.72)

   at OpenQA.Selenium.Navigator.GoToUrl(String url)

Microsoft Edge WebDriver 119.0.2151.72
Microsoft Edge Version 119.0.2151.72 (Official build)

From a different build agent with the same Edge WebDriver and Version it works fine, it happens only in one on my build agents.

Thank you in advance

Hi @itzhakja , it looks like one of the headless tab processes may be crashing during the test run. Are you able to share a code sample and minimal web page that reproduces the issue?

We are also having this issue. I cant seem to reproduce it in a sharable sense because I am not sure exactly what's causing it just yet.

We are using the runner images from microsoft (windows-2022) and they did an update with the 120 edgedriver and 120.00 browser version.

Note: If it's ran with MicrosoftEdge=120.0.2210.77 & and Edgedriver 119 it works fine.

@bwalderman I am facing same issue after my Azure windows-2022 image that I am using for Selenium UI job upgraded to
Microsoft Edge 120.0.2210.61, Microsoft Edge Driver 120.0.2210.61

Before that everything worked as expected on:
Microsoft Edge WebDriver 119.0.2151.97 and Microsoft Edge Driver 119.0.2151.97 .

The newer versions of Edge are also have that error:
Microsoft Edge WebDriver 120.0.2210.121
Microsoft Edge Driver 120.0.2210.121

We could isolate the problem in our szeanrio. Maybe it also applies to others. The reason for us was that we set the environment variable WEBVIEW2_ADDITIONAL_BROWSER_ARGUMENTS to --remote-debugging-port=9222

Now when opening for example Outlook and afterwards started our target application for testing, we got the error. When we did not start Outlook there was no error.

Our solution was to remove the environment variable from windows settings and set the environment variable only for the target application.
