Pm2 and Nginx wont communicate and SSL handshake failed

Hello I am fairly new to ubuntu and pm2 and Nginx but have been having this inconsistent problem for a few days and have no clue how to fix it as google doesn't tell me anything. Keep it me it used to work and now it dosent.

So in short I have set up Nginx with the config below.

server {

         root /home/ubuntu/apps/bachelor-app/client/build;

        # Add index.php to the list if you are using PHP
        index index.html index.htm index.nginx-debian.html;

        server_name vizdatathesis.com www.vizdatathesis.com;

        location / {
                        try_files $uri /index.html;
                        }

         location /api {
                     proxy_pass http://localhost:3005;
                        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;
        }
    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/vizdatathesis.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/vizdatathesis.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}

server {
    if ($host = www.vizdatathesis.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    if ($host = vizdatathesis.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot
        listen 80;
        listen [::]:80;
        server_name vizdatathesis.com www.vizdatathesis.com;
    return 404; # managed by Certbot
}

Pm2 logs return

Error: listen EADDRINUSE: address already in use :::3005

  code: 'EADDRINUSE',
  errno: -98,

  address: '::',
  port: 3005
}

However it tells me everything is up and running.

Nginx gives me this error:

2022/05/18 16:34:53 [crit] 25410#25410: *1209 SSL_do_handshake() failed (SSL: error:0A00006C:SSL routines::bad key share) while SSL handshaking, client: x.x.x.x, server: 0.0.0.0:443
2022/05/18 18:11:32 [notice] 1107#1107: signal process started

I am overwhelmed with errors at this points and have no clue where the root of the problem is. I have tried to restart both pm2 and nginx but it didnt help. The sites shows the nginx but gets net::ERR_CONNECTION_REFUSED when trying to reach the server.
