ConnectionAbortedError: [WinError 10053] An established connection was aborted by the software in your host machine
Solution 1
This error message...
ConnectionAbortedError: [WinError 10053] An established connection was aborted by the software in your host machine
...implies that the initialization of a new WebBrowsing Session i.e. Firefox Browser session was aborted.
An established connection was aborted by the software in your host machine
As per your code attempt the error is clearly coming out create_webdriver_instance()
function which contains:
try:
ua_string = random.choice(ua_strings)
profile = webdriver.FirefoxProfile()
profile.set_preference('general.useragent.override', ua_string)
return webdriver.Firefox(profile)
And:
except IndexError as error:
print('\nSection: Function to Create Instances of WebDriver\nCulprit: random.choice(ua_strings)\nIndexError: {}\n'.format(error))
return webdriver.Firefox()
So it is not exactly clear from which function you are facing this issue among return webdriver.Firefox(profile)
or webdriver.Firefox()
.
Perhaps a closer look at the logs within codepen suggests the error is coming out from webdriver.Firefox(profile)
.
Reasons
There can be multiple reason behind this error:
- Presence of anti-virus softwares.
- Firewall blocking the ports.
- Network Configuration.
- Problem can be caused by CORS.
- Due to enabling of HTTP keep-alive connections
Solution
The initial step would be find out if any software is blocking the connection to/from the server in your computer. Apart from that the probable solutions are:
- Disable anti-virus softwares.
- Disable firewall.
-
Ensure that /etc/hosts on your system contains the following entry:
127.0.0.1 localhost.localdomain localhost
As per Connection was aborted by the software in your host machine you need to allow localhost routes like
http://localhost:8080/reactive-commands
-
AutomatedTester: This issue is not because we are not connected at the time of doing a request. If that was the issue we would be getting a httplib.HTTPConnection exception being thrown. Instead a BadStatusLine is thrown when we do a connection and close it and try parse the response. Now this could be the python stdlib bug, httplib bug or selenium bug. A Python client to replace urllib with something else that does not exhibit the same defect with Keep-Alive connections is WIP.
andreastt: The geckodriver team is working on extending the server-side timeout value to something more reasonable. As I said, this would help mitigate this issue but not fundamentally fix it. In any case it is true that five seconds is probably too low to get real benefit from persistent HTTP connections, and that increasing it to something like 60 seconds would have greater performance.
Conclusion
Selenium 3.14.0
has just been released. If you are affected by this issue please upgrade accordingly.
References:
- Flask broken pipe with requests
- Cross-Origin Resource Sharing (CORS)
- Connection was aborted by the software in your host machine
- [WinError 10053] with the 0.21.0
- Keep-Alive connection to geckodriver 0.21.0 dropped after 5s of inactivity without re-connection using Selenium Python client
- Support keep alive connections
- Struct hyper::server::Server
- Urllib3
Solution 2
As documentation says:
Software caused connection abort. An established connection was aborted by the software in your host computer, possibly due to a data transmission time-out or protocol error.
Possible reasons:
- Timeout or other network-level error.
- Network connection died
- Firewall closed the connection because it was open too long
- Connection was closed before process has been finished
- AntiVirus blocks the connection
and etc.
Also try to downgrade geckodriver 0.21.0
to geckodriver 0.20.1
. You can download it here. It seems to be a problem with geckodriver 0.21.0
https://stackoverflow.com/a/51236719/8625512
PS:
options.add_argument('-headless')
should be:
options.add_argument('--headless')
Solution 3
This problem happened to me and as the error was intermittent, I initially believed that it was some firewall or antivirus problem, but it was much simpler.
I had a form that was being submitted twice when the SEND button was clicked. The button was set to type="submit" and a javascript code submitted this form when this button was clicked. I changed the button to type="button" and the problem was solved.
Solution 4
Another reason:
When a page served by python is loading, user may cancel the loading before transmission is complete, by pressing Esc or by clicking 'X'(Stop loading this page button). This is usually done when the server is slow.
E.g. if user navigates to your page and Press Esc before the image is fully loaded, this error will occur. In that case, you have to Handle it.
Solution 5
Windows has implemented Controlled folder access, which is to block un-authorized app to access your important files(means almost anything installed by windows). This is to prevent data encryption and ransom by malware.
Windows will pop-out notification if it blocks any app.
You can allow apps/programs access through Controlled folder access.

For some reason I get the following error only when I open up a nested
webdriver
instance. No idea what is happening here.I am using Windows 10, geckodriver 0.21.0, and Python 3.7.

geckodriver.log
Here it is in a codepen, since it is wayyy too long!
create_webdriver_instance Function
def create_webdriver_instance(): options = Options() options.add_argument('-headless') try: ua_string = random.choice(ua_strings) profile = webdriver.FirefoxProfile() profile.set_preference('general.useragent.override', ua_string) return webdriver.Firefox(profile) # profile, firefox_options=options except IndexError as error: print('\nSection: Function to Create Instances of WebDriver\nCulprit: random.choice(ua_strings)\nIndexError: {}\n'.format(error)) return webdriver.Firefox() # firefox_options=options
Does anybody have any idea whatsoever what might be causing the connection to abort?-
Andrei Suvorkov over 5 yearsCould you show please what
create_webdriver_instance()
does? -
oldboy over 5 years@AndreiSuvorkov of course. i'll add it right now
-
K. Dackow over 5 yearsWhat does the geckodriver.log file say?
-
oldboy over 5 years@K.Dackow first thing when i wake up tomorrow ill run that part of the script again and post the geckodriver.log and ill send you a msg to notify u
-
oldboy over 5 years@K.Dackow ok, ive added the geckodriver.log in a codepen since it puts me way over the character limit. tbh i have no idea what i am or should be looking for in it :/
-
K. Dackow over 5 yearsI'm not entirely sure either, but usually search for ERROR or EXCEPTION within it to try and diagnose the issue!
-
oldboy over 5 years@K.Dackow that's what i was thinking. there are numerous errors throughout it, so when i get some time i'm gon have to take a closer look
-
-
oldboy over 5 yearscan you take a look at the
geckodriver.log
i just posted to the codepen in my question?!?! im not sure what to look for in it?? -
Andrei Suvorkov over 5 yearsCould you please provide a code where you are creating a nested webdriver. Also please describe the process. Are you closing the parent webdriver before child is finished?
-
oldboy over 5 yearsi already provided the code where i create the "nested" webdriver.
_ff
is the nested webdriver, and no i'm not closing the parent (ff
) before i close_ff
-
oldboy almost 3 yearsthere were extensions running in your webdriver instance?! didnt even know this was possible o: chrome? firefox?
-
oldboy almost 3 yearsglad to hear that
-
Adrian Skar almost 3 yearsNo, I'm sorry I didn't clarify. I got this error in the browser's console not in a webdriver.
