Allowing Frame cross-origin - nginx

Question

In this script, my server is nginx.sample.com. It enabled CORS
nginx.sample.com:8080 # tomcat and host with the same server
I got Error message:
Uncaught DOMException: Blocked a frame with origin "http://nginx.sample.com" from accessing a cross-origin frame.
at HTMLIFrameElement.document.getElementById.onload (eval at _evaluateScript (http://nginx.sample.com/app/a4j/g/3_3_3.Final/org/ajax4jsf/framework.pack.js:2346:14), <anonymous>:7:116)
I already add "add_header Access-Control-Allow-Origin *;" to my configuration but no luck
and Here is my nginx configuration files:
/etc/nginx/conf.d/wildfly.conf
upstream wildfly {
server nginx.sample.com:8080 weight=100 max_fails=5 fail_timeout=5;
}
server {
listen 80;
server_name nginx.sample.com;
add_header Access-Control-Allow-Origin *;
location / {
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-Server $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://wildfly/;
}
}
/etc/nginx/nginx.conf
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
# Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;
events {
worker_connections 1024;
}
http {
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 4096;
include /etc/nginx/mime.types;
default_type application/octet-stream;
include /etc/nginx/conf.d/*.conf;
}
Is there a way to configure nginx so my nginx.sample.com:8080 and proxywebsite1.com are not seen as different by the browser?
I'm using nginx/1.20.1
Thanks
