How to test Apache Reverse proxy enablement for JSON API

I have Installed an SSL/TLS certificate and Configured Apache with SSL/TLS and then Configured the reverse proxy by setting

ProxyPass /api
ProxyPassReverse /api

Now, I am not able to test it, How do i know whether HTTPS is enabled for JSON API or not. I am launching the JSON API using below command.

DAML_SDK_VERSION=2.1.1 daml json-api
–ledger-port 7575 --address --log-level DEBUG

Browsing is not working. Request to provide solution for this.
