title: pyzabbix Zabbix sender
body: <p>I am looking to send a few items to zabbix using Zabbix-Sender function of pyzabbix. As a test I am running the below code - </p>
  
  <pre><code>from pyzabbix import ZabbixMetric, ZabbixSender, ZabbixResponse
  metrics = []
  m= ZabbixMetric('mme01', 'TEST', 20)
  metrics.append(m)
  ZabbixSender('10.46.224.5').send(metrics)
  </code></pre>
  
  <p>I made this snippet after reading the document - <a href="https://py-zabbix.readthedocs.io/en/latest/sender.html" rel="nofollow noreferrer">https://py-zabbix.readthedocs.io/en/latest/sender.html</a></p>
  
  <p>When I run the snippet I get the error - </p>
  
  <pre><code>AttributeError: 'ConnectionRefusedError' object has no attribute 'msg'
  </code></pre>
  
  <p>I have verified IP connectivity </p>
  
  <p>Can Anyone help ?</p>
