<p class="MsoNormal">This is not uncommon on some corporate networks, they are doing MITM checks and blocking the certificate checks. You might need to see if they have a specific certificate that you should now be using. There is some openssl option to disable

</span>You might need to do something curl calls against the s3 url and see what the certificate is that is being used and see if its no longer signed by amazon but by your companies certificate.<o:p></o:p></p>
