laravel websocket with nuxt and nginx reverse proxy returns 502

The Configuration that I have is now is working on ssl, So Im sharing each file.Ill be giving a brief explanation at the end.

Before you start make sure you have copied your own full ssl_ciphers from YOUR_SITE_NAME.YOUR_DOMAIN_SUFFIX.ssl.conf if you have any.

Laravel V8 ,LaravelWebSocket version 1.4,pusher 4.0

server {
  listen zzz.zzz.zzz:80;
    server_name example.com www.example.com;
        return 301 https://www.example.com$request_uri;

}

For nginx config if you are running centos 7 try copy this in terminal cd /etc/nginx/conf.d/vhosts hit enter then ls you will see YOUR_SITE_NAME.YOUR_DOMAIN_SUFFIX.conf and YOUR_SITE_NAME.YOUR_DOMAIN_SUFFIX.ssl.conf which codes provided above,

• Keep in mind in both you have change example to your domain name and zzz should be your servers IP Address
• You can try 127.0.0.1 on zzz too if your internet IP address didnt work
• Keep in mind to check the root and logs address that it might be different than mine
• fastcgi_pass can be localIP or internetIP too which for me was internetIP before I do a major update which involved backend/frontend/server update but now its localIP

After the setup make sure to restart nginx and websocket services and perform a php artisan cache and config clear.after that do a fresh nuxt build and connect to your laravel-websockets via the link https://www.example.com/laravel-websockets

Im using this configuration for a site with ssl on nginx+nuxtjs+laravel+laravel-websocket+pusher

Hopefully this answer will make you connect successfully
