Problem

I had the same problem running InternetExplorerDriver locally in Windows 7 - (IEDriverServer_Win32_2.42.0.zip)

org.openqa.selenium.remote.UnreachableBrowserException: Error communicating with the remote browser. It may have died. 

When I checked the running processes under TaskManager, there were multiple IEDriverServer.exe processes running, that hadn't been cleaned up properly.

Solution

Running the following command, killed all running IEDriverServer.exe processes, and resolved this issue (for me).

taskkill /F /IM IEDriverServer.exe 

回答2:

For me using a port starting with a 1, rather than a port close to the default port value 5555, caused me to have this error. Changing the node port from 1234 back to 5558 has solved the issue. Not sure how ports work but it seems 1234 was unstable

I followed these steps and the problem got resolved:

1. get the firefox profile name

   • try this command on run window firefox.exe -P or firefox.exe -P or firefox.exe -profilemanager

One of the above command will open pop up stating the name of Default profile which is nomaly "default"

2. Use below mentioned code for gettingthe firefox driver

   ProfilesIni allProfiles = new ProfilesIni(); FirefoxProfile myProfile = allProfiles.getProfile("default"); myProfile.setAcceptUntrustedCertificates(true); myProfile.setAssumeUntrustedCertificateIssuer(true); driver = new FirefoxDriver(myProfile); 

回答4:

Take all new version of jars and run again the project ,it will work

回答5:

Please try to replace exe path with below command

File file = new File("IE DriverServer.exe path"); System.setProperty("webdriver.ie.driver", file.getAbsolutePath());
