Selenium protect ports [duplicate]

My Chrome browser is updated to version 78 and when I tried to execute any code of automation, it shows the error
Please protect ports used by ChromeDriver and related test frameworks to prevent access by malicious code.
[1573451703.668][WARNING]: Timed out connecting to Chrome, retrying...
Nov 11, 2019 11:25:05 AM org.openqa.selenium.remote.ProtocolHandshake createSession
INFO: Detected dialect: W3C
[1573451709.039][WARNING]: Timed out connecting to Chrome, retrying...
How can I fix it?

This error message...
Please protect ports used by ChromeDriver and related test frameworks to prevent access by malicious code.

...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.
Analysis
The first log message:
Please protect ports used by ChromeDriver and related test frameworks to prevent access by malicious code.
is part of the startup log when using ChromeDriver and is informative in nature.
You can find a detailed discussion in How do I protect the ports that chromedriver use?
The following log message:
[1573451703.668][WARNING]: Timed out connecting to Chrome, retrying...
indicates there are some incompatibility between the version of the binaries you are using.
Solution
Ensure that:
JDK is upgraded to current levels JDK 8u222.
Selenium is upgraded to current levels Version 3.141.59.
ChromeDriver is updated to current ChromeDriver v78.0 level.
Chrome is updated to current Chrome Version 78.0 level. (as per ChromeDriver v78.0 release notes)
Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
(WindowsOS only) Use CCleaner tool to wipe off all the OS chores before and after the execution of your Test Suite.
(LinuxOS only) Free Up and Release the Unused/Cached Memory in Ubuntu/Linux Mint before and after the execution of your Test Suite.
If your base Web Client version is too old, then uninstall it and install a recent GA and released version of Web Client.
Take a System Reboot.
Execute your #Test as non-root user.
Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.

I have fixed this issue of timeout / Connection reset by changing my code from:
public void AfterScenario(Scenario sc) {
driver.close();
driver.quit();
driver = null;
}
to:
public void AfterScenario(Scenario sc) {
driver.quit();
driver = null;
}
So basically I removed the driver.close() and this fixed my issue. I do not know why this is happening, but experts can explain more...

I had to update to the dev version of chrome 79 and the latest dev version of chromedriver to make it work. Although I've run against other issues with this version, so I don't know if its a good solution.

C# Google Chrome Selenium URL Navigation with BinaryLocation

Greetings StackOverflow Community,
My issue is simple. I have the following five lines of code, that I can't figure out why Google Chrome doesn't launch google.com when using a custom binary location.
var Chrome = new ChromeOptions();
Chrome.AddArgument("no-sandbox");
Chrome.BinaryLocation = #"C:\GoogleChrome\chrome.exe";
ChromeDriver driver = new ChromeDriver(#"C:\ChromeDriver", Chrome);
driver.Navigate().GoToUrl("https://www.google.com");
Any ideas? All I get is the default chromedriver URL of "data:," when Google Chrome launches.
Why isn't the driver.navigate command working when using a Chrome.BinaryLocation? If I comment out that line, than it works fine.
I am using the following:
Windows 7
Visual Studio Community Edition 2017
Google Chrome version 67
chromedriver 2.41
.NET 4.5 Bindings

hey i dont think you need of binary location
And maybe Chrome is already a type,
try this:
ChromeOptions options = new ChromeOptions();
options.AddArgument("no-sandbox");
var driver = new ChromeDriver(#"C:\GoogleChrome", options);
driver.Navigate().GoToUrl("https://www.google.com");

Okay, I found the answer to this question. I don't know why the Portable version of either Firefox, Chrome or other Chromium based browsers do not function this way, but I resolved this issue by copying the enterprise installation files from program files for Chrome to another directory on the computer and then pointing the Selenium script to use that binary location. Then it worked just fine.
It was also useful to point Chrome to a custom chrome profile location to keep more of the Chrome application from using the local users's AppData folder.
If anyone is interested in accomplishing the same task, I can provide some example code that accomplishes this task. Just message me for more details.

Selenium with Microsoft Edge driver never finishes initialising

I'm using the C# bindings for Selenium and trying to get a simple automated test in Microsoft Edge working.
class Program
{
static void Main(string[] args)
{
EdgeOptions options = new EdgeOptions();
options.PageLoadStrategy = EdgePageLoadStrategy.Eager;
RemoteWebDriver driver = new EdgeDriver();
driver.Url = "http://bing.com/";
}
}
But the program halts on the initialisation of the EdgeDriver, the edge browser launches but the url never changes to "bing.com".
Has anyone else experienced this?

I have faced the same issue. I followed the below steps to resolve it :-
Download the correct Microsoft WebDriver server version for your build.
How to find your correct build number :-
1- Go to Start > Settings > System > About and locate the number next to OS Build on the screen. This is your build number. Having the correct version of WebDriver for your build ensures it runs correctly.
2- Run this command systeminfo | findstr /B /C:"OS Version" this will give the output like OS Version: 10.0.10586 N/A Build 10586. Here is build number is 10586
You need to check your Windows OS build number and download appropriate .msi and install it.
Provide the Syetem property where MicrosoftWebDriver.exe installed to webdriver.edge.driver.
Note :- The Default installed location of the MicrosoftWebDriver.exe :-
for 64 bit is C:\Program Files (x86)\Microsoft Web Driver
for 32 bit is C:\Program Files\Microsoft Web Driver
Hope it will work...:)

This happens when your system does not match the webdriver version... Determine which release of Windows 10 you are using... then go here and download same release..
https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver
Here's what the error looks like when the versions don't match.
Selenium will Hang
EdgeOptions options = new EdgeOptions();
options.PageLoadStrategy = EdgePageLoadStrategy.Eager;
RemoteWebDriver driver = new EdgeDriver();
driver.Url = "http://bing.com/";
Results in this exception with Edge still up and on the Bing page
Exception Thrown
changing the code to this, with no options:
var driver = new EdgeDriver();
driver.Url = "http://bing.com/";
Results in this:
Exception thrown: 'System.InvalidOperationException' in WebDriver.dll
And this in the console.
Something's not right with the MicrosoftWebDriver.Exe which was downloaded from here. https://www.microsoft.com/en-us/download/details.aspx?id=48212 and installed into the Program Files folder by default. Here's screenshot of add/remove programs. System is Windows 10 PRO 64 bit.
Note I did not try the 32 bit version

Selenium IEDriver / Firefox Driver browser location Error

unexpectedly I am experiencing this issue. I am trying to run my testcase. For Firefox or IE browser but I don't know where is the issue. It cannot find the browser location.
Selenium.WebDriver -Version 2.52.0
Selenium.Support -Version 2.52.0
Selenium.RC -Version 2.52.0
Selenium.WebDriverBackedSelenium -Version 2.52.0
It was working perfectly but soon after I updated my nupackages. I am having this issue. Also I tried to use previous version but now I am having same problem in that one as well.
Error:
IEDriver
FirefoxDriver Error
Enviorment Variable
Installed Location:
C:\Program Files (x86)\Google\Chrome\Application\chrome.exe
C:\Program Files\Mozilla Firefox\firefox.exe

Make sure you're mentioning path of IEDriverServer executable in PATH variable of your system.
echo $PATH
https://github.com/SeleniumHQ/selenium/wiki/FirefoxDriver
https://github.com/SeleniumHQ/selenium/wiki/InternetExplorerDriver

It happened to me as well. I tried to download older version from the below link and it worked. Let me know, if that helped. About IE I am trying to figure it out what should be the case.
Firefox version download
You don't need to alter your code. Also Anderson is right you probably might have downloaded x64 version and I think Selenium might be trying to find x86 version (in Program File) which might have caused the problem.

For IE Driver download it (32bit) LINK
After that your browser init need to be something like that:
InternetExplorerDriverService driverService = InternetExplorerDriverService.CreateDefaultService();
driverService.HideCommandPromptWindow = true;
driverService.LibraryExtractionPath = #"c:\drivers\"; // here is your driver location
InternetExplorerOptions options = new InternetExplorerOptions();
options.EnableNativeEvents = true;
options.IgnoreZoomLevel = true;
options.IntroduceInstabilityByIgnoringProtectedModeSettings = true;
driver = new InternetExplorerDriver(driverService, options, TimeSpan.FromSeconds(180));
For Firefox just try to update the firefox to last version.

Again timeout creating new FirefoxDriver with Firefox 43 and above

With latest Selenium WebDriver v 2.50.00 I am getting (again) following exception:
Failed to start up socket within 45000 ms. Attempted to connect to the
following addresses: 127.0.0.1:7055
executing:
driver = new FirefoxDriver(new FirefoxBinary(), firefoxProfile, pageLoadTimeout);
This happens with version 43 and higher of Firefox. I have downgraded Firefox to v. 39 and there it works OK.
It seems that this issue happened before couple of times with various versions of Selenium and Firefox, see here or here.
Any workaround for this or downgrading Firefox and waiting for a new version of Selenium WebDriver is the only way?

Yes, It is bug which still going to resolve for latest versions
You need set the Preferences as xpinstall.signatures.required", false.
Below code is working for me but it is in java. you get the idea where you need to change
WebDriver driver = null;
final FirefoxProfile firefoxProfile = new FirefoxProfile();
firefoxProfile.setPreference("xpinstall.signatures.required", false);
driver = new FirefoxDriver(firefoxProfile);
driver.manage().window().maximize();
driver.get("https://www.google.co.in/");
Hope it will help you :)
