workbench error 10060 while connecting to Mysql AWS RDS instance
<p>I have set up a mysql RDS instance which accepts connection from anywhere within our organization. I have set up an user for this instance as well.</p>

<p>Few days back user complained that workbench can not connect to this instance and getting the error : Lost connection to MySQL server at 'waiting for initial communication packet', system error: 10060</p>

<p>It used to work for him, but all of a sudden it stopped working. Not sure what user has done between when it worked and now. Anyways, I have done the following troubleshooting steps:
1. did telnet 'rds end point' 3306 from this terminal and noticed connection is there
2.I tried to connect to this instance from my machine using workbench, heidisql and mysql cmd prompt utilities...every time it works
3.reset his password (just for trying)<a href="http://i.stack.imgur.com/MvCsM.png" rel="nofollow">see attached</a>, but problem persists</p>

<p>Thoughts? workbench version is 6.1 CE and user is on windows 7</p>
