How to set up reverse proxy ssl for the wordpress category or post page

Hello, i am trying to set up a reverse proxy ssl for my wordpress domain. I have been able to set up the reverse proxy ip ssl for the wordpress, but it only apply for the main homepage. When i try to access the post or category or any other link inside the WordPress, it return with an error : 404 Not Found

I have been trying to find a solution or a guide regarding this, but so far i can not find how to solve this.

This is an example of how my set up for the reverse proxy

server {
        listen 80 default_server;
        server_name _;
        return 301 https://$host$request_uri;
}

server {
        #listen 80 default_server;
        #listen [::]:80 default_server ipv6only=on;

        listen 443 ssl ;
        listen [::]:443 ssl default_server;

        #ssl on;
        ssl_certificate         /etc/nginx/certificate.crt;
        ssl_certificate_key     /etc/nginx/private.key;

        root /var/www/html;
        index index.php index.html index.htm;

        server_name localhost;

        location / {

                proxy_pass https://example.com;
                proxy_ssl_server_name on;
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ =404;
                # Uncomment to enable naxsi on this location
