SSL: WRONG_VERSION_NUMBER ON PYTHON REQUEST

Question

Python version: 3.9.1

I trying to write bot that send requests and it work perfectly fine, the only issue that i have is when i trying to use web debugging programs such as Charles 4.6.1 or Fiddler Everywhere. When I open it to see bot traffic and response form server it crash showing me this error:

(Caused by SSLError(SSLError(1, '[SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1124)')))

I used to have this issue and I was able to fix it by simply adding verify=False to my request, but right now it does not work.

I had the same problem. It's a bug in urllib3. You have to specify your proxy in the request, and change the 'https' value to 'http'.

My example:

proxies = {'https': 'http://127.0.0.1:8888'}
request = r.get('https://www.example.net', verify=False, proxies=proxies)

Specify proxy means? Am getting this error without any proxy also. – Abhinav Rai Mar 22 '21 at 01:36

Not verifying the https connection is not a solution, but an insecure hack. – atlau Nov 04 '21 at 10:00
https has to be changed by http in the `r.get([...])`. – Simon Provost Dec 07 '21 at 15:20
Thanks man.. I was becoming desperate already.. – Allar Feb 25 '22 at 02:42
Many thanks. Yes, after fiddler starts up, the url request failed again and again. Configuring the fiddler proxy in code works well. – Diri Jianwei Guo Jun 22 '22 at 06:50
Thank Bryan, that was what I need it to fix my problem. – Pizzaboy Sep 13 '22 at 14:50
This is not a valid solution. It is virtually never appropriate to simply disable TLS. – Resigned June 2023 Sep 29 '22 at 05:55
I also solved with this solution but got a different error (somehow website cannot redirect when using the proxy with `http`) – Khaerul Umam Jan 05 '23 at 03:21
@atlau is that turning of verification to the end server, or just to the proxy, though? Disabling verification of a server running on localost is pretty safe, IMO. – Aaron Lehmann Feb 07 '23 at 15:49

Try this answer.

In short you should downgrade urllib:

pip3 install urllib3==1.23

If anyone else is having this issue in 2023, simply updating the urllib3 library worked for me.

python -m pip install --upgrade urllib3

I had the same problem but i solved it by changing the "https" in the URL to "http":

Example:

ulr_example = 'https://example.com'

to

url_example = 'http://example.com'
