Trying to connect with edge browser from excel using Selenium. It was working fine until new edge version was upgraded. But it is not working now, I am getting an error: session not created: DevToolsActivePort file doesn't exist.

Hi @Rajgafoor Basheer, Mohamed SSSCCH-FO/ROP , Thanks for your code. However, I couldn't reproduce this issue. Everything works fine. Here're some possible solutions you can try: Make sure you are using the latest version of Microsoft Edge and Edge driver. Kill all the processes of Microsoft Edge before you run the code. Add Bot.AddArgument ("--disable-dev-shm-usage") Bot.AddArgument ("--no-sandbox") before Bot.Start "edge" VBA Selenium is using a much older version. If none of the above works for you, you can switch to latest Selenium 4 with other languages. If the answer is helpful, please click "Accept Answer" and kindly upvote it.

Kill all the processes of Microsoft Edge before you run the code.

Add Bot.AddArgument ("--disable-dev-shm-usage") Bot.AddArgument ("--no-sandbox") before Bot.Start "edge"

Thanks for helping me with your answer. Still getting this error, not sure this is because of some system settings.

Hi @Rajgafoor Basheer, Mohamed SSSCCH-FO/ROP, Normally, "--no-sandbox" and "--disable-dev-shm-usage" options can solve this kind of problem. Since you are using older version of Selenium, I suggest you upgrade to the latest Selenium 4 with other programming languages, and check again.

@ShiJieLi-MSFT Hi, I am using Selenium Edge webdriver to connect to my existing WebView2 instance(already set system variable on my local machine for remote-debugging-port for the webview2 before webview2 launch) launched by my Windows application, and am receiving the same error and also the error below:

selenium.common.exceptions.WebDriverException: Message: disconnected: not connected to DevTools (failed to check if window was closed: disconnected: not connected to DevTools) (Session info: MicrosoftEdge=123.0.2420.97)
