SSLError (just started, this was working yesterday)

Here is a traceback, I use braintree in my django app.

SSLError: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:590)

So, I'm not sure if this is a requests issue or how braintree is using requests. Pretty odd though!

[teewuane]

Oops, just read the "PLEASE NOTE" on the README about requiring TLSV1.2. I'll try and figure this out.

[teewuane]

Found some guidance here: https://github.com/paypal/tls-update#python

[teewuane]

Hmm. I'm still not able to get this working. I am on Mac OS Sierra. It is up to date.

This is what I have installed in my virtualenv.

braintree (3.32.0)
Django (1.10.4)
pip (9.0.1)
psycopg2 (2.6.2)
requests (2.12.4)
setuptools (30.0.0)
wheel (0.29.0)

Using python2.7

Hi @teewuane ! You're right, this sounds like it's related to the TLS 1.2 requirement. I'd recommend reaching out to Braintree support for help with the specifics of your integration.

[Tyrdall]

I've updated the braintree (3.33.0) and requests (2.12.4) packages and now it works again.

I had to reinstall XCode and update brew and pyenv. Here are the commands I used:

#Update XCode 
#Restart machine
$ brew update
$ brew upgrade pyenv
$ pyenv install 3.4.6 # newest 3.4.x of Python
$ pyenv global 3.4.6 # set as default version of python
$ pyenv virtualenv 3.4.6 myenv
$ pyenv activate myenv
$ pip install -r requirements.txt

Hope that's useful to someone someday.
