Python HTTPConnectionPool Failed to establish a new connection: [Errno 11004] getaddrinfo failed
Question:
I was wondering if my requests is stopped by the website and I need to set a proxy.I first try to close the http’s connection ,bu I failed.I also try to test my code but now it seems no outputs.Mybe I use a proxy everything will be OK?
Here is the code.
import requests

'date': date,

'img': img[0]
}
def main(offset):
flag = 1
html = get_page_index(offset, '光伏')
for url in parse_page_index(html):
html = get_page_detail(url)
if html:
data = parse_page_detail(html)
if data:
html_parser = HTMLParser()
cwl = html_parser.unescape(data.get('content'))
data['content'] = cwl
print(data)
print(data.get('img'))
flag += 1
if flag == 5:
break
if __name__ == '__main__':
pool = Pool()
pool.map(main, [i*20 for i in range(10)])
and the error is the here!
HTTPConnectionPool(host='tech.jinghua.cn', port=80): Max retries exceeded with url: /zixun/20160720/f191549.shtml (Caused by NewConnectionError('<requests.packages.urllib3.connection.HTTPConnection object at 0x00000000048523C8>: Failed to establish a new connection: [Errno 11004] getaddrinfo failed',))
By the way, When I test my code at first it shows everything is OK!
Thanks in advance!
Answers:
It seems to me you’re hitting the limit of connection in the HTTPConnectionPool. Since you start 10 threads at the same time
Try one of the following:
- Increase the request timeout (seconds):
requests.get('url', timeout=5)
- Close the response:
Response.close(). Instead of returning response.text, assign response to a varialble, close Response, and then return variable
When I faced this issue I had the following problems
I wasn’t able to do the following
– The requests python module was unable to get information from any url. Although I was able to surf the site with browser, also could get wget or curl to download that page.
– pip install was also not working and use to fail with following errors
Failed to establish a new connection: [Errno 11004] getaddrinfo failed
Certain site blocked me so i tried forcebindip to use another network interface for my python modules and then i removed it. Probably that cause my network to mess up and my request module and even the direct socket module were stuck and not able to fetch any url.
So I followed network configuration reset in the below URL and now I am good.
In case it helps someone else, I faced this same error message:
Client-Request-ID=long-string Retry policy did not allow for a retry: , HTTP status code=Unknown, Exception=HTTPSConnectionPool(host='table.table.core.windows.net', port=443): Max retries exceeded with url: /service(PartitionKey='requests',RowKey='9999') (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x000001D920ADA970>: Failed to establish a new connection: [Errno 11001] getaddrinfo failed')).
…when trying to retrieve a record from Azure Table Storage using
table_service.get_entity(table_name, partition_key, row_key).
My issue:
- I had the
table_name incorrectly defined.
My structural URL was incorrect (after ".com" there was no slash and there was a coupling of another part of the url)
Sometimes it’s due to a VPN connection. I had the same problem. I wasn’t even capable of installing the package requests via pip. I turned off my VPN and voilà, I managed to install it and also to make requests. The [Errno 11004] code was gone.
