Getting lots of these errors

Since this morning i am getting lots of these errors:

2019-06-10 12:17:12 ERROR (MainThread) [homeassistant.core] Error doing job: SSL handshake failed
Traceback (most recent call last):
  File "/usr/local/lib/python3.7/asyncio/", line 625, in _on_handshake_complete
    raise handshake_exc
  File "/usr/local/lib/python3.7/asyncio/", line 189, in feed_ssldata
  File "/usr/local/lib/python3.7/", line 763, in do_handshake
ssl.SSLError: [SSL: NO_SHARED_CIPHER] no shared cipher (_ssl.c:1056)

What is wrong and how to get rid of them?
Plus, it means i have installed python 3.7 release? I am asking this as if i check python release i get the following:

pi@hassbian:/$ python --version

Python 2.7.13

pi@hassbian:/$ python3 --version

Python 3.5.3


What is the right release for running HA and do i need to upgrade for the 0.95 release working ?

Your errors appear to be related to https , unrelated to python version.
You do not directly say, but it appears you are running Hassbian. You would need to check the Python version in its venv. The release Notes direct you on how to upgrade python for Hassbian.

sudo hassbian-config upgrade python

Yes thanks, i run hassbian but i cannot get the latest release of hassbian-config.
Can you tell me how to upgrade ?

Their documentation is a mess right now. Try this

sudo hassbian-config upgrade hassbian
