Whenever I try to establish a socket connection (from client) with my server (writen in nodejs), I get a cors error Access to XMLHttpRequest at 'https://example.onrender.com/socket.io/?EIO=4&transport=polling&t=P1g4kQB' from origin 'http://another-example-website.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
