python Errno 10054 An existing connection was forcibly closed by the remote host

Question

I am writing python to crawl Twitter space using Twitter-py  I have set the crawler to sleep for a while  2 seconds  between each request to api twitter com  However  after some times of running  around 1   when the Twitter s rate limit not exceeded yet  I got this error    Errno 10054  An existing connection was forcibly closed by the remote host    What are possible causes of this problem and how to solve this   I have searched through and found that the Twitter server itself may force to close the connection due to many requests   Thank you very much in advance

I know this is a very old question but it may be that you need to set the request headers. This solved it for me.

For example 'user-agent', 'accept' etc. here is an example with user-agent:

url = 'your-url-here'
headers = {'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.75 Safari/537.36'}
r = requests.get(url, headers=headers)

there are many causes such as    The network link between server and client may be temporarily going down  running out of system resources  sending malformed data    To examine the problem in detail  you can use Wireshark   or you can just re-request or re-connect again

This can be caused by the two sides of the connection disagreeing over whether the connection timed out or not during a keepalive   Your code tries to reused the connection just as the server is closing it because it has been idle for too long   You should basically just retry the operation over a new connection   I m surprised your library doesn t do this automatically

For me this problem arised while trying to connect to the SAP Hana database  When I got this error    OperationalError  Lost connection to HANA server  ConnectionResetError 10054   An existing connection was forcibly closed by the remote host   None  10054  None    I tried to run the code for connection mentioned below   which created that error  again and it worked          import pyhdb     connection   pyhdb connect host  example com  port 30015 user  user  password  secret       cursor   connection cursor       cursor execute  SELECT  Hello Python World  FROM DUMMY       cursor fetchone       connection close      It was because the server refused to connect  It might require you to wait for a while and try again  Try closing the Hana Studio by logging off and then logging in again  Keep running the code for a number of times
