Socket.io.js Failed to load resource: the server responded with a status of 404 ()

[PhovDeWae]

Hello.

I have a problem with socket.io in my app https://weather-radio365.netlify.app/client/. My app make socket connection to server when a client connects immediatly. The error occurs with the same description as title of the topic. But when I run my app locally, everything is fine.
On the client side I create a socket object by io.connect(). I tried also io().connect() and io( "https://weather-radio365.netlify.app/client/", {"rejectUnauthorized" : false}).connect(), but the result the same.

It is my first time when I deploy the project. So I don’t know what details I have to provide or how configure socket connection. Thanks.

The static portion of your application builds via CI and deploys to CDN, and then any runtime server side functions (or API’s) that you integrate with must either be running elsewhere, or be implemented via Serverless functi…
