UnificationEngine: Unable to send Requests via Python using TLS or SSL
<p>I am attempting to use a Raspberry Pi 3 (Model B) to send Requests by Python to the Unification Engine. With SSL/TLS verification disabled, the request happens normally, but I need to get SSL/TLS working with it.</p>

<p>The below code is meant to force a session to use TLSv1 for the purpose of sending Python Requests to UnificationEngine:</p>

<pre><code>class ForceTLSV1Adapter(HTTPAdapter):
    def init_poolmanager(self, connection, maxsize, block=False):
        self.poolmanager = PoolManager(num_pools=connection,maxsize=maxsize,block=block,ssl_version=ssl.PROTOCOL_TLSv1)

def proxy_manager_for(self, proxy, **proxy_kwargs):
    proxy_kwargs['ssl_version'] = ssl.PROTOCOL_TLSv1
    return super(ForceTLVS1Adapter, self).proxy_manager_for(proxy, **proxy_kwargs)

----Some Code here----

s = requests.Session()
s.mount('https://apiv2.unificationengine.com', ForceTLSV1Adapter())

----Some Code Here----
</code></pre>

<p>However, this error pops up after I send the request.</p>

<p>I'm not sure what is the issue right now.</p>

<p>Looks like the certificate verification isn't done correctly.
Have a look at:
