UPdating the servers Erased Nginx and caused issues, please help

so last weekend I updated and upgraded the severs. In order for the server to keep the updates I had to upgrade the server. Upon doing so it erased my nginx configuration. I had set it up again However, I clearly missed a step. What did I do wrong?

when I do nginx -t

I get this: ginx: [emerg] cannot load certificate “/etc/nginx/certificate/nginx-certificate.crt”: PEM_read_bio_X509_AUX() failed (SSL: error:0909006C:PEM routines:get_name:no start line:Expecting: TRUSTED CERTIFICATE) nginx: configuration file /etc/nginx/nginx.conf test failed

We don’t have ssl certificates yet. BUt by next weekend we should have them.

This is my nginx configuration (we are gonna use wild card certificates)

server {
        listen 80;
        listen [::]:80;
        server_name *.kosherup.xyz;
        return 301 https://$host$request_uri;
}


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

        ssl_certificate /etc/nginx/certificate/nginx-certificate.crt;
        ssl_certificate_key /etc/nginx/certificate/nginx.key;

		ssl_protocols TLSv1.1 TLSv1.2 TLSv1.3;
  		ssl_ciphers ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384;
  		ssl_prefer_server_ciphers on;

        add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;

        root /var/www/api.kosherup.xyz/html;

        index index.html index.htm index.nginx-debian.html;
        server_name *.kosherup.xyz;

        location /socket.io {
            proxy_pass http://localhost:4000;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "Upgrade";
            proxy_set_header Host $host;
        }

        location /v1 {
                    proxy_pass http://localhost:4000;
           }
}
