Invalid:error connecting to backend after clicking on API publisher test button
<p>I Configured WSO2 Api Manager product on unix environment.I am able to login carbon,publisher and store url by using DNS name of server.By using below url I am able access carbon, publisher page::</p>

<p><strong><a href="https://abc.xx:9445/carbon" rel="nofollow noreferrer">https://abc.xx:9445/carbon</a></strong></p>

<p>For testing purpose I deployed sample application in publisher.
Url I am try to hit from publisher API::
<strong><a href="https://abc.xx:9445/am/sample/pizzashack/v1/api" rel="nofollow noreferrer">https://abc.xx:9445/am/sample/pizzashack/v1/api</a></strong></p>

<p>But After clicking on test button(i.e. production endpoint) by using DNS name of server it gives me <strong>Invalid:error connecting to backend</strong>.Checked log it shows connection timeout for **<a href="https://abc.xx:9445/am/sample/pizzashack/v1/api" rel="nofollow noreferrer">https://abc.xx:9445/am/sample/pizzashack/v1/api</a>**url.</p>

<p>If I use IP instead of DNS name it gives me <strong>bad certificate</strong> error in log.</p>

<p>Any help will be appreciated!!</p>
