title: Unable to connect to any of the specified MySQL hosts issue in Production Environment
body: <p>I was looking in posts similar to mine, but didn't find any response to my issue.</p>
  
  <p>Recently the MySql server was changed, right now I'm using a different one,</p>
  
  <p>I use this connection string in my asp.net vb web application project:</p>
  
  <pre><code>&lt;add key="MySQLConnStr" value="server=xx.xxx.x.xx; user id=mysql_link;  database=mysql; pooling=false; password=xxxx"/&gt;
  </code></pre>
  
  <p>Ok when I run the WebApp in my computer (development environment) it works perfect, now, in the host (production env.) I get the "Unable to connect..." error.</p>
  
  <p>What could be the problem here??? I just changed the old MySql server ip for the new one.</p>
  
  <p>I restarted the application pools in the host, restarted the webapp as well, but nothing.</p>
  
  <p>thanks in advance!    </p>
