How to solve websocket issue on node js?

Question

Node.js

When connecting, sometimes in the browser console there is such an error

Connection closed before receiving a handshake response

What is most likely the problem? In the ws module itself , or is it due to the fact that all my code is now executing synchronously, and the connection does not have time to be processed?

Answer 1

Increase the handshake timeout.
In general, use asynchrony and promises - this is NodeJS.
