    <description>&lt;P&gt;We have a Qlik Sense on Windows deployment in AWS with a VPC setup.&lt;/P&gt;&lt;P&gt;We are able to install and run it successfully. Here are some scenarios tested:&lt;/P&gt;&lt;P&gt;- Qlik Sense Hub and QMC &lt;STRONG&gt;is accessible&lt;/STRONG&gt; inside the server.&lt;/P&gt;&lt;P&gt;- Qlik Sense Hub and QMC &lt;STRONG&gt;is accessible&lt;/STRONG&gt; outside the server but within the same VPC.&lt;/P&gt;&lt;P&gt;- Qlik Sense QMC &lt;STRONG&gt;is accessible&lt;/STRONG&gt; via Apache web server reverse proxy.&lt;/P&gt;&lt;P&gt;- Qlik Sense Hub &lt;STRONG&gt;is not accessible&lt;/STRONG&gt;&amp;nbsp;via Apache web server reverse proxy.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Since the deployment is in a VPC Network, outside access to Qlik Sense must pass through a reverse proxy.&lt;/P&gt;&lt;P&gt;We are using an Apache Web Server as a reverse proxy going to Qlik Sense. QMC can be access just fine, however, hub is throwing a connection lost error. Please refer to below screenshot.&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Hub_Landing_Error.jpeg" style="width: 577px;"&gt;&lt;img src="https://community.qlik.com/t5/image/serverpage/image-id/42306i4C5A166A70DC16D4/image-dimensions/577x325?v=v2" width="577" height="325" role="button" title="Hub_Landing_Error.jpeg" alt="Hub_Landing_Error.jpeg" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;As for the apache web server reverse proxy events, please refer into the image below:&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="ApacheWebServer_Log.jpeg" style="width: 999px;"&gt;&lt;img src="https://community.qlik.com/t5/image/serverpage/image-id/42307i1D2362D5BF35B15E/image-size/large?v=v2&amp;amp;px=999" role="button" title="ApacheWebServer_Log.jpeg" alt="ApacheWebServer_Log.jpeg" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I would like to seek for your assistance in order to get through this challenge. I don't have any idea where to check the cause throwing these errors, as well as to solve this concern.&amp;nbsp;&lt;/P&gt;</description>
