I am using Python 3.4 on OSX Yosemite

[Lukasa]

Python 3.4, OS X Yosemite, Requests 2.7.0: I cannot reproduce this bug. =) Can you consistently hit it? What requests version are you using?

[sigmavirus24]

Also, what version of openssl and do you have pyOpenSSL installed?

[kristjanr]

requests 2.7.0
OpenSSL 1.0.2 22 Jan 2015
I did not have pyOpenSSL installed.

I installed the latest version of pyOpenSSL 0.15.1 and ran the same request again.
Still the same result.

[sigmavirus24]

Are you behind a proxy?

[kristjanr]

No, I am not behind a proxy.

[kristjanr]

I consistently get this problem. By now, I have tried with 3 different networks.

As soon as you are sure that this problem is not relative to requests, we can drop this :) because I only have this problem on my dev machine. Our production environment is Ubuntu and the request to the same url works fine there.

But until then, I am more than happy to give all the information you need for debugging.

[Lukasa]

The OpenSSL version number you gave us: how did you obtain it?

[kristjanr]

I typed in "openssl version" in the terminal:

Kristjans-MBP:leech kristjan$ openssl version
OpenSSL 1.0.2 22 Jan 2015

And for the one in Python:

>>> import OpenSSL
>>> OpenSSL.__version__
'0.15.1'

[Lukasa]

Sorry, can you do

import ssl
print ssl.OPENSSL_VERSION

[kristjanr]

>>> import ssl
>>> ssl.OPENSSL_VERSION
'OpenSSL 0.9.8zd 8 Jan 2015'

[Lukasa]

Awesome, so you're using a very old OpenSSL version. How did you install Python 3?

[kristjanr]

I used Mac OS X 64-bit/32-bit installer from here https://www.python.org/downloads/release/python-340/

[Lukasa]

Weird, I thought that bundled a newer OpenSSL. I recommend installing it using Homebrew, which will link against a newer OpenSSL.

[kristjanr]

What about macports? I use this as my package manager.

I don't know about macports: you'll want to check with them whether they compile against the system OpenSSL or against one they provide.

[mieciu]

If somebody still encounters this issue on their OS X stack I'll strongly recommend reinstalling Python 3 from https://www.python.org/downloads/ rather than homebrew - I've faced exactly the same thing and this was a proper solution for me 😄

[sigmavirus24]

@mieciu thanks for the input. That said, my recommendation is to use homebrew. 😉

EOF occurred in violation of protocol (_ssl.c:590) i am getting this error.
do this
import requests
sess = requests.Session()
adapter = requests.adapters.HTTPAdapter(max_retries = 1000)
sess.mount('http://', adapter)

and do sess.post() but still got the same error. could you guys help me it that???

[Lukasa]

@biplab-dholey This error can occur for a number of reasons. The retries count is unrelated. This error results from your TLS configuration, and without more information it's very difficult for us to help.

[flyaway921]

I hit this error and I finally find I was accessing a none HTTPS service with a HTTPS protocol.
