XMLHttpRequest cannot load. Origin is not allowed by Access-Control-Allow-Origin.

I have followed this guide

for every class loading I get this error:
XMLHttpRequest cannot load. Origin is not allowed by Access-Control-Allow-Origin.

I am trying to create a standalone parse server, keeping the website that accesses it separate, they have separate domains, both are https.

I have tried modifying the nginx "/etc/nginx/sites-enabled/default" file. under location I have tried

location /parse/ { proxy_set_header 'Access-Control-Allow-Origin' '*'; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-NginX-Proxy true; proxy_pass http://localhost:1337/; proxy_ssl_session_reuse off; proxy_set_header Host $http_host; proxy_redirect off; }

Have also tried

location /parse/ { add_header 'Access-Control-Allow-Origin' '*'; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-NginX-Proxy true; proxy_pass http://localhost:1337/; proxy_ssl_session_reuse off; proxy_set_header Host $http_host; proxy_redirect off; }

I have also tried adding this entire script

It seems to be an issue with the express server in parse-server that nginx is proxying to. I have been unable to figure out how to modify this. Help is appreciated.

Thanks for the response, using this post: cors_heroku_parse-server I was able to fix the issue by forking the server and adding cors
