CORS policy

[gravit22]

When I try to upload my app on web server, I got this error has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
How to resolve it?

Fix your web server settings?

How?

Depends on your web server setup, obviously.

I do not understand. I uploaded files of template project on free web hosting. I have access to .htaccess file, and I tryed to add there
<IfModule mod_headers.c> Header set Access-Control-Allow-Origin "*" </IfModule>
But it didn't work, and I am asking for help.

Resolved by adding appropriate headers and registering SSL.
But there is another error:
TypeError: WebAssembly.instantiate(): Import #0 module="__wbindgen_placeholder__" error: module is not an object or function

Whatever. I just hosted it on github pages and it works.
