OpenQA.Selenium.WebDriverException : No response from server for url #3719

lukeis · 2016-03-03T22:53:11Z

Originally reported on Google Code with ID 3719

When using ChromeDriver via ChromeDriverService and RemoteDriver
and run multiple tests. They _sometimes_ fail with the exception above.

The tests run OK when I start individual ChromeDriver per each unit test.

The stack is as follows:

OpenQA.Selenium.WebDriverException : No response from server for url http://localhost:50258/session/e58704878fbaecee8aaefabe64076eeb/element/:wdc:1334321221530/click

lukeis · 2016-03-03T22:53:14Z

I'm still seeing this with latest chromedriver, grid, and selenium.  

Running tests on the local computer through chromedriver works great, but I run tests
through a grid(on the local machine) the failure rate goes way up - lots of these No
Response exceptions.

lukeis · 2016-03-03T22:53:15Z

I see this error with windows 2003 R2, firefox 13, using webdriver.
it just started occuring recently, for me.

Also with the most recent chromedriver this happens frequently as well
on windows XP sp3 with chrome 20, 21, or 22. i resorted to disabling the updates for
chrome to keep the chrome 20 driver able to work.

I've read elsewhere that it may be a request limit (for proxy servers having too low
of a conection limit), that causes the server to return null and crash with the "No
response from server for url" exception. 

The "No response from server for url" exception seems to occur whenever a request by
the server returns null or an empty response at which point the server crashes.

It Might be a load related issue, as in when the load of requests is too much for the
drivers to carry, then they throw the  "No response from server for url" exception

All my tests broke today with the following error

OpenQA.Selenium.WebDriverException : No response from server for url http://localhost:7057/hub/session/283a5d58-82dd-483b-a3ef-0ff3ee37841c/element

Am on WebDriver C# bindings 2.25.1 Win 7,FF 14/13

They all worked fine until early today nothing has been changed.
However if i rerun them again they work alright a few times.

Are we going to get a fix for this in future releases ?

cheers,

Hi, I'm solved it
if there are no timeout (based on machine speed - usually thread.sleep(250) works fine)
between interactions with driver - driver couldn't throw event from browser to test
- and you gets error.

And watch at some "Explicit Implicit Wait Webdriver" articles.

I started seeing this issue primarily with Chrome 21.  The Thread.Sleep method is not
a good long term solution for this though.

Am not sure if it's triaged or some developer has even looked at this issue.

Having most of our testcase failures has resulted in an annoyance for
effort spent on understanding what is happening !!

We also get consistently get this error using the latest Chrome/Chromedriver, and are
desperatefor a fix.  Will investigate how to rollback to a previous version of Chrome
without it auto-updating itself and see if we can regain functionality.

Hi Guys,

I'm seeing the same thing in FF14 Windows Server R2 2008.... What is the best workaround
for this, I saw many post that adding some thread.sleep will solve the issue, but not
sure if that is best solution......

We're getting it too with our tests.  I'm running Win7 x64, FF14, Chrome21.  We're using
the Fire Fox driver for our tests against SQL Server Reporting Services reports and
the errors are consistent with certain reports but not with others.

The issue is reproducing both for Selenium 2.40 java and c# , just tested with java-maven
for my app and the same error is throwed on Firrefox and Chrome, for IE it works with
no problem. The element which is causing me this problem is a button that when you
click then a new Window is opened... Any ideea why is this happening? is Selenium Webdriver
bug " The HTTP request to the remote WebDriver server for URL "?

But in most cases that his happens on some url, if the server returned 404 isn't the
entire page shouldn't load?

Is the resource u got 404 error on, is the exact url you were looking for or did you
tried to navigate to a full url page and only that pic failed to return?

I just wanted to say that, in response to post #42, this issue DOES still occur in IE.
I am using the latest version (2.41.0) of Selenium for C# and the 32-bit IEDriverServer,
and I have found a case in which clicking on a certain button produces this error ("The
HTTP request to the remote WebDriver server for URL [...] timed out after 60 seconds")
100% of the time. Unfortunately, this occurs in a web application that isn't publicly
available, but I am currently attempting to create a minimal test case to share publicly.
In the meantime, I at least wanted to point out that the problem still occurs in IE.

#55 Hi Daniel,
 have you managed to make the test case to reproduce this issue? I am having this issue
in both FF & Chrome (everything in a latest version - selenium server 2.41, C# binding
2.41, ChromeDriver 2.10, latest version of chrome & ff). I'd be very grateful if you
could post the test case to Selenium devs to work this out.

Thanks,

Marcel,

Sorry, I was never able to reproduce the issue, despite my best efforts. This issue
came up while I was working with a previous employer; unfortunately, I no longer have
access to that web application. All I can say is, I suspect that it either had something
to do with Classic ASP (the back end; I don't know much about ASP...), or, more likely,
due to the fact that we were clicking on an element which was located in a frame (and
the element had a Javascript "onclick" attribute). I'm sorry that I was unable to come
up with a test case; I hope that someone else succeeds and the issue gets resolved.

Daniel

Can you try to run your test on virtual machine?

proxy.HttpProxy = "127.0.0.1:8877";

var options = new ChromeOptions();
options.Proxy = proxy;

return new ChromeDriver(options);

Okay I ran the same tests on another VM and they worked - I'm assuming there's an issue
with the firewall here, specifically there's a popup window that comes up right after
you run the tests for the very very first time, I can't remember what it said now though,
something about vstest...

Hi all, 

I'm also getting this error from time to time. I was not able to find out where the
problem is but what I can tell for sure is that once we encounter this we can't run
tests against the nodes unless we restart them. 

We built a library for testing, basically a wrapper over Selenium with some other functionality
the we found useful. We also open sourced the library: https://github.com/AutoScout24/SeleniumTestLibrary


As I said, once the problem appears we must restart the java processes that start the
nodes. What is also interesting is that the problem appears while tests are running.
That is, from 200 tests, let's say, some will pass and some will not. 

As the nodes are useless once the problem appears and after some googleing, I suspect
that in my case there's a lock happening somewhere. The library that we are using is
reading the output file and almost instantly it continues with the next test suite,
so basically new request that can be on the same URI as the last one used. The last
change that we did and we are currently testing, is to continue with the testing only
after we are done reading the output file. We don't know yet whether this fixed our
problem or not. Test is in progress.

Do you have a similar scenario? Can you reuse, retry the request once the problem appears
or not? Maybe this is relevant, maybe not, but at least we know something more. 

Hope this helps! 
Mario.

Hi,

I found the following facts in my testing. If I run the test and the browser window
is visible, i.e. from the IDE or using a batch file it works fine. As soon as I run
the task in automated mode through a task then the test will not work. This happens
using either FF or Chrome drivers. You can verify this by trying this page https://www.horizonutilities.com/pages/login.aspx

Using the chrome driver i get the following error. Chrome doesn't even load this page
Exeption: WebDriver The HTTP request to the remote WebDriver server for URL http://localhost:65315/session/337172c9e02776077b2025d9aa16cf80/element
timed out after 60 seconds. ---------------

With the FF driver I get the following error
Exeption: WebDriver [JavaScript Error: "a.document.getElementsByTagName(...)[0].getButton
is not a function" {file: "file:///C:/Users/electrocrawler/AppData/Local/Temp/anonymous.6b519c69a3894ef9af8de966e29bc542.webdriver-profile/extensions/fxdriver@googlecode.com/components/command-processor.js"
line: 8877}]'[JavaScript Error: "a.document.getElementsByTagName(...)[0].getButton

line: 8877}]' when calling method: [nsICommandProcessor::execute] ---------------


Again, this error will only happen when the test runs hidden, i.e. the browser window
not visible, otherwise it works fine.

I run the hidden tasks using Windows Task Manager with the option to 'run the task
whether the user is logged on or not'. It fails every time with this option. Switching
to 'run only when the user is logged on', works fine every time.

Hi, 

I can confirm Daniel's findings. 
When I start the Selenium clients in a background process I get the error mentioned.
If the processes run in foreground everything is fine. 

I also find out that version 36 from Chrome doesn't have this problem and so I downgraded
to this version. Now the tests run fine but not with the latest version. 

Mario.

My workaround is to fire up a chromedriver.exe in session and call it using remotedriver
on http://localhost:9515

This will work even if the user has disconnected from the remote terminal (but the
session is still active).

Closing the issue as it is related to old version of chromedriver.
If the issue is still actual raise an issue on the chromedriver tracker [1] and profice
a reproduction case (if possible)

chromedriver is a separate project that has its own tracker (as stated above), please
report the issue there.

Also you should not expect a browser to work in headless environment (with no GUI).

Reported by barancev on 2014-11-04 19:41:20

This issue affects both chrome driver and firefox driver. Out of 10 or so automated
testing sites that I support, 8 of them work great when running in a background task,
but the 2 sites I mention, will not. I am unable to understand why these site will
only work in an active session while the rest will work well either way.

Thanks,

Reported by dkaminski on 2014-11-04 21:18:56

Write to the browser's issue tracker and request them to implement ability to work without
GUI :)

Or use headless browsers like PhantomJS. Or use xvfb to provide GUI. Or setup a virtual
lab with real GUI sessions to run browsers in.

If it can help people here.

I had the same problem with error messages like :
error: The HTTP request to the remote WebDriver server for URL http://localhost:62966/session/47a49deeba88be7092a9c435bd4c903e/window/current/maximize
timed out after 60 seconds

I had them only with chromeDriver (2.12) and on my CI server (Windows 2012R2, CruiseControl.NET
used as a Windows Service).
If I ran the tests locally I had no problem. I had no problem on the CI Server with
a graphic User Session too.

I think this is caused by request being sent too early to the driver, the driver does
not catch them and they are lost for everyone.

I work around this issue by using the ChromeDriverService and RemoteWebDriver. Either
instanciated outside the code or within the code before any test is run works fine.
You'll see examples at the end of 
https://sites.google.com/a/chromium.org/chromedriver/getting-started

Hope this helps.

To elaborate.

Remote (RDP) on to your server.

Execute ChromeDriver.exe, it will open on port 9515.

Run your tests with Nunit (jenkins / teamcity agent)

The tests will open and run as long as there is a RDP session connected.

Its definitely not a glamorous solution, but it resolves the issue.

In single test there is no exception.

Hi All

I've been getting the same issue. I tried a suggested solution here to run RemoteWebDriver
pointing to an Uri. My client application couldn't connect to the chromedriver.exe
I've started and fails with...

"socket could not be performed because the system lacked sufficient buffer space or
because a queue was full"

This seems to be an issue with TCP/IP port exhaustion or am I barking up the wrong
tree?
