Problem

This is the configuration to run a Reverse Proxy on standard https port 443 infront of API Manager backend.

The Apache Web Server is version 2.4.7 on Linux Mint 17.3

Apache is setup for HTTPS with a certificate and the browser for API Manager will need to trust this certificate.

Apache is not verifying the certificate of API Manager although this would need to change in secure environments.

Resolution

Here is the VirtualHost configuration from the Apache conf file

ServerName milnerm.wks.dubl.axway.int

    #LogLevel info ssl:warn
