AppWorks Mobile app fails to connect on HTTPS port

Hi,
Having installed and configuring AppWorks 16.5, I am running into an issue where the mobile app fails to connect with the following error:

If I navigate to the URL in a browser it opens as expected,

The sever.xml file is configured as outlined in the installation guide (using a self-signed certificate):

<Connector  port="9092"
    protocol="org.apache.coyote.http11.Http11NioProtocol"
    maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
    clientAuth="false" sslProtocol="TLS"
    keystoreFile="c:\cert\ghataura.jks"
    keystorePass="ghataura"
    keyAlias="otappworks"
    keystoreType="jks"
/>

In the gateway.log I see the following:

2019-02-13 06:46:59,4262019-02-13T06:46:59,426 [localhost-startStop-1] INFO otag.util.HostContainer - Used InetAddress to resolve host otappworks.ghataura.com

As with the configured http, should the configured https port also be detected? I am not sure why it reports Multiple https Connectors detected in server.xml as there is only 1 configured https port.

Additionally is it following error normal to be reported?
