I have deployed a MERN stack chat application on Render.com, and while basic functionalities like login and registration are working fine, the real-time chat functionality is failing. The application works as expected locally, but not after deployment.
Below type of error I get.
Failed to load resource: net::ERR_CONNECTION_REFUSED index-Q4Sg5fsh.js:428
GET http://localhost:3000/socket.io/?EIO=4&transport=polling&t=OxY6Y47 net::ERR_CONNECTION_REFUSED
Any suggestions are highly appreciated. Help me to achieve real-time functionality.
I expect to send and receive all chats in real. If you can help me with notification and typing functionality that would be great.
but every time I refresh the page then I am able to see the new chat msg

I can't comment so writing it here
You might want to update your cors settings for deployment
cors: {
// at line 47
origin: "http://localhost:5173" // frontend server
}
