redirect from http (port 80) to https (port 443) not working

Hi,

I am running nginx version: nginx/1.16.1 on CentOS Linux release 7.8.2003

(Core). When I hit https://marketplace.mydomain.com it works perfectly fine

whereas when I hit http://marketplace.mydomain.com (port 80) does not get

redirected to https://marketplace.mydomain.com (port 443). I have the below

nginx.conf.

server {

> listen 443 ssl default_server;

> #listen 80 default_server;

> #server_name _;

> server_name marketplace.mydomain.com;

> ssl_protocols TLSv1.2;

> ssl_certificate /etc/ssl/certs/

> marketplace.mydomain.com/fullchain1.pem; ssl_certificate_key

> /etc/ssl/certs/marketplace.mydomain.com/privkey1.pem;
