Just in case, try to hide the header on nginx side (nginx.conf and nginx.ssl.conf) inside location / block where is the proxy_pass directive:

proxy_hide_header 'Access-Control-Allow-Origin';

Reload nginx and try again… also, remove cache or history for that site in your browser.

/home/admin/conf/web/domain.com/nginx.conf

have add in this file but

where i find the file nginx.ssl.conf …

If you don’t have one in the same dir, then you have not enabled ssl for that site so no need to edit nginx.ssl.conf

yes im using cloudflare ssl. thats why

please check screen short did i add code on right place ? there is 2 place where is proxy_pass

thanks for help im sorry im not good in coding

I don’t use Cloudflare so I won’t be able to help here but maybe Cloudflare is caching the headers and you would need to purge it on Cloudflare side.

Also, you could try to connect to your site directly (without Cloudflare) maybe you would need to add the ip and domain in your hosts file to be able to access and check whether it works or not. Also, if you use Firefox or Chrome you can use their dev tools to inspect the site and check the headers your browser is receiving and you will see whether the allow origin is the right one or it isn’t.

For me the solution is:

Edit /home/user/conf/web/domain/nginx.ssl.conf file, add this line under “location ~* ^.” part:

add_header Access-Control-Allow-Origin "*";

Then reload nginx, delete site cache (for example for Symfony project: php bin/console cache:clear)

be sure to read the first 4-5 lines in the header of that file…
