here is my fix, and it worked

i added this to the server block in nginx conf file. 

proxy_redirect http:// https://;

or you can make it more strict to do it only on your domain, for example in my case it will be: 

proxy_redirect http://skyerp.net https://skyerp.net;

i tested it and it worked. so try it out

Hello @James Quinlan,

Thanks for your reply, but I try this method which is not working. I am using an Apache service. Please help me to solve the problem.

You need to modify your server configuration.

In the nginx conf file, within the location block, you should add the line

add_header Content-Security-Policy upgrade-insecure-requests;
