Question

I am using react as my font end, and nodejs as backend which is running on localhost:3016 and I used nginx as reverse proxy and load balancer; this my nginx conf file for the site

upstream load_balance{
    #least_conn;
     #ip_hash;
    server  localhost:3016;
    #server localhost:8010;
    #server localhost:8011;
    #server localhost:8012;
    #server localhost:8013;
    #server localhost:8014;
    #server localhost:8015;
    #server localhost:8016;
    #server localhost:8017;
    #server localhost:8018;
}

server {

    # SSL configuration
    #
    # listen 443 ssl default_server;
    # listen [::]:443 ssl default_server;

I get this error

2.2664eafa.chunk.js:2 Mixed Content: The page at 'https://www.ethiolive.net/' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://192.168.8.101:3016/catagorey/getMainCategorie'. This request has been blocked; the content must be served over HTTPS.``` from chromes console, I think I am missing something on the nginx configuration, thanks

Configure your nodejs to generate the pages with the correct HTTPS urls. — Gerald Schneider, Dec 09 '21 at 09:10

I found the solution for the problem, and I believe sharing the solution would be helpful for others, use this 'proxy_set_header Content-Security-Policy upgrade-insecure-requests; below is how I configured

location /api {
                proxy_pass http://load_balance;
                proxy_http_version  1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection 'upgrade';
                proxy_set_header Host  $host;
                proxy_cache_bypass $http_upgrade;
                proxy_set_header   X-Real-IP         $remote_addr;
                proxy_set_header   X-Forwarded-For   $proxy_add_x_forwarded_for;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_read_timeout 3600;
                proxy_headers_hash_max_size 512;
                proxy_headers_hash_bucket_size 128;
                proxy_set_header Content-Security-Policy upgrade-insecure-requests;

hope you find it helpful!
