Hub Error: Connection Lost via Apache Web Server Reverse Proxy

[markticoy]

We have a Qlik Sense on Windows deployment in AWS with a VPC setup.

We are able to install and run it successfully. Here are some scenarios tested:

- Qlik Sense Hub and QMC is accessible inside the server.

- Qlik Sense Hub and QMC is accessible outside the server but within the same VPC.

- Qlik Sense QMC is accessible via Apache web server reverse proxy.

- Qlik Sense Hub is not accessible via Apache web server reverse proxy.

Since the deployment is in a VPC Network, outside access to Qlik Sense must pass through a reverse proxy.

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.

As for the apache web server reverse proxy events, please refer into the image below:

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.
