NPM and Bitnami-Wordpress-nginx http content problem.

[akarakn]

``Hi, everyone.
I have a droplet that is running NPM and Bitnami-WordPress-Nginx.
I added a proxy with SSL, HTTPS scheme, and port 8443 of WordPress-Nginx container. But there is a problem with content, As far as I understand my theme has some HTTP-only content, and it couldn't load. it works without SSL. How I can solve this issue?
As far I understand something rewrite the link of content with https.

# ------------------------------------------------------------
# <myDomain>
# ------------------------------------------------------------
server {
  set $forward_scheme https;
  set $server         "wordpress";
  set $port           8443;

  listen 80;
listen [::]:80;

listen 443 ssl http2;
listen [::]:443 ssl http2;
  server_name <myDomain>;
  
  # Let's Encrypt SSL
  include conf.d/include/letsencrypt-acme-challenge.conf;
  include conf.d/include/ssl-ciphers.conf;
  ssl_certificate /etc/letsencrypt/live/npm-1/fullchain.pem;
  ssl_certificate_key /etc/letsencrypt/live/npm-1/privkey.pem;

    # Force SSL
    include conf.d/include/force-ssl.conf;

proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $http_connection;
proxy_http_version 1.1;

  access_log /data/logs/proxy-host-3_access.log proxy;
  error_log /data/logs/proxy-host-3_error.log warn;

  location / {

    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection $http_connection;
    proxy_http_version 1.1;

    # Proxy!
    include conf.d/include/proxy.conf;
  }
  # Custom
  include /data/nginx/custom/server_proxy[.]conf;
}
