On January 21, 2019, we will be blocking all manual/custom integrations using the TLS 1.0 and 1.1 encryption protocols so that we can upgrade to only TLS 1.2 in order to apply the industry’s current best practice for security.
Please make sure your manual/custom integration with Pipedrive is updated to TLS 1.2.
If you have any questions about this change, please feel free to ask below.
Hello how can i know if my manual/custom integration with Pipedrive is updated to TLS 1.2._???
Can you tell me which programming language and version you’re using? Then, we can look it up.
This is my error:
ERROR:
[SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:645)
Django Version: 1.10.4
Exception Type: SSLError
Exception Value:
[SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:645)
Exception Location: C:\Users\acamue.AHDISENO\AppData\Local\Programs\Python\Python35\lib\ssl.py in do_handshake, line 633
Python Executable: C:\Users\acamue.AHDISENO\AppData\Local\Programs\Python\Python35\python.exe
Python Version: 3.5.2
You’re most definitely not using TLS 1.2, but where the roadblock is, is actually quite hard to guess 
It looks like there is something in your flow trying to use TLS V1. Maybe a silly question, but have you tried starting from that do_handshake method and go backward to see what module or function is trying to establish the connection? Most probably that needs to be updated or some parameters need to be changed.
Let’s see if someone else can be more helpful…
