title: MySQL connection Refused from a particular IP address
body: <p>I have a remote server say 1.2.3.4 where I run a code to connect to MySQL which is on another (third) remote server. Now the piece of code runs perfectly fine from my local machine (It connects to Mysql on the Remote server), and that piece of code runs well from two other different IP addresses also.</p>
  
  <p>But only from 1.2.3.4 server when I try to connect to MySQL it gives this Error:</p>
  
  <blockquote>
    <p>OperationalError: (2003, "Can't connect to MySQL server on '45.105.149.250' (110)")</p>
  </blockquote>
  
  <p>What can be the Issue ?  </p>
