Python Error 104, connection reset by peer

Question

I have been having this error when trying to make web requests to various hosts. After debugging a bit I have found the solution is updating the requests[security] through pip.

Answer 1

I was running into this issue as well with Python2.7 requests. Installing "requests[security]" with pip brought a clear improvement for me but out of 1000 requests in rapid succession, I would still get this error 2 or 3 times.

Resolved to implementing retries as this seems to be a very temporary issue. Works like a charm now.

import time
import requests
from requests.exceptions import ConnectionError

# ...

nb_tries = 10
while True:
    nb_tries -= 1
    try:
        # Request url
        result = session.get("my_url")
        break
    except ConnectionError as err:
        if nb_tries == 0:
            raise err
        else:
            time.sleep(1)

# ...

Answer 2

Run

sudo python3 -m pip install "requests[security]"

or

sudo python -m pip install "requests[security]"

to fix this issue.
