I'm running Abntecart through the docker container. I can view the site and admin panel. When I create new order it's saying the connection is not secure. After searching through forums, I have been advised to setup HTTPS communication. I have found nginx SSL configuration in Abantecart GitHub repo. After applying the configuration, I can access the store via HTTPS, but I'm getting a blank page.

I have reinstalled abantecart from fresh. This time I didn't enable HTTPS. I can view the store. If I click any product, I'm getting a blank page.
Please find the attached logs files
