Sorry for the delay.
Could you send me the configuration files ?. You do not need to post the configuration file here, we have a Support Tool that will gather relevant information for us to review your configuration. Could you please download and execute it on the machine where the stack is running by following the steps described in the guide below?
How to Run the Bitnami Support Tool
The redirections can be normal if the request are to a Hostname and wp to server in other hostname. As apache do not log the headers sent/returned, Could you log in one the servers and run the following commands ?
$ curl -vsD - 'http://18.104.22.168/' -o /dev/null
$ curl -vsD - 'http://localhost/' -o /dev/null
And then paste here what they return.
