Getting ('Connection aborted.', OSError(0, 'Error') errors with python requests

Question

I'm trying to write code to login to a website.
First I tested using ARC. It works fine. Image

So I wrote python code like this:

import requests   url = 'https://www.bible.ac.kr/login.aspx/' headers = {     'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64; Trident/7.0; rv:11.0) like Gecko',     'Referer': 'http://www.bible.ac.kr/' }   req = requests.get(url, headers=headers) # OR requests.get(url, headers=headers, verify=False)  print(req.status_code) 

but I got errors.

Error

I have not solved this problem for a long time.
Only when I run Fiddler, the code works fine. I don't know the reason.
Even though I tried using C language, I still got an error on this website.
Can you solve this problem using only Python?

Answer 1

I solved the problem using OPENSSL 1.0.1f.

The domain only supported TLS 1.0, SSLv2, and SSLv3. These protocols are outdated and rarely used. So I doubted the compatibility of OPENSSL 1.1.1 series. As a result, using openssl version 1.0.1f solved the problem. However, using older openssl in Python may require extra work.

I'm not very good at English, but I hope this helps.
