SSLV3_ALERT_HANDSHAKE_FAILURE error about django-push-notifications HOT 13 CLOSED

Not sure why it's doing a ssl3 handshake, it should do something like tls1x

from django-push-notifications.

Isn't it because in _apns_create_socket (line 48) you have

sock = ssl.wrap_socket(sock, ssl_version=ssl.PROTOCOL_SSLv3, certfile=certfile)

?

I'm running on python 2.6 and I also had this issue. I replaced the aforementioned line with:

    sock = ssl.wrap_socket(sock, ssl_version=ssl.PROTOCOL_TLSv1, certfile=certfile)

And I'm no longer having any issues.

I have same problem. @sorter solution worked for me.

Also only PROTOCOL_TLSv1 worked, PROTOCOL_TLSv1_2 will not work

from django-push-notifications.

Same issue. Has anything changed from Apple?

from django-push-notifications.

I got one error about this via Sentry on my system and that was it.

Did apple do something and then undo-it?

I can’t replicate the error and I haven’t changed anything.

just revert the fix on my own server and see that the problem is still here. I also noted that only sandbox server is having problem, non sandbox server (my production server) is still working normally.

PROTOCOL_TLSv1_2 is only available on Python 3.4+. On my Mac, I can confirm this with

/Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/ssl.py
/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/ssl.py

from django-push-notifications.

And yes, Apple sandbox gateway has stopped supporting SSL3. See

from django-push-notifications.

I have a PR for this

#92

from django-push-notifications.

Fixed

from django-push-notifications.

Given the seriousness of the issue I will be doing a 1.2 release now with this fix in.
