Ubuntu 18.04 lts nginx server issue with origin

Hi there,

I am still new to Linux/Ubuntu 18.04 lts and have been using Nginx recently.
Has anyone have a solution/ideas what shall I do to enable “Origin” for the smooth exchange of requests and data between php(folder1) + vue(another folder) ? When I try to open links in my vue get CORS policy prohibited action as the localhost differs in localhost:8000 on default and for vue :8080.
My project consists of two folders 1st: php + dbconnection & 2nd vue admin part.
Second question, Is it related to my nginx conf, or is it more Ubuntu authorization part?
I will be looking after to your answers.

here is my virtual host config for nginx :

server {
listen 80;
server_name somelocal;
root /home/some/some/some/VirtualHost3/public;
add_header ‘Access-Control-Allow-Origin’ ‘*’;
add_header ‘Access-Control-Allow-Headers’ ‘origin, x-requested-with, content-type’;

    index index.php index.html index.htm;
    # add_header Access-Control-Allow-Origin *;

    # serve static files directly
    location ~* \.(jpg|jpeg|gif|css|png|js|ico|html)$ {
           access_log off;
            expires max;
            log_not_found off;

    location / {
            # add_header Access-Control-Allow-Origin *;
            try_files $uri $uri/ /index.php?$query_string;

    location ~* \.php$ {
  #  try_files $uri = 404;
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;

location ~ /\.ht {
            deny all;
