Websocket connection issues with NodeJS app using SocketIO on app engine

[Oluwatobi Omotayo]

I just deployed my NodeJS application on app engine, the applications uses SocketIO for real time functionalities. When I run the application in the browser the web socket aspect of the app fails.

I keep getting this kind of error logs in my browser console "WebSocket connection to 'wss://talk-bot-f6dd1.appspot.com/socket.io/?EIO=3&transport=websocket&sid=VkY63uHqxve1i8EOAACk' failed: WebSocket is closed before the connection is established." What do I have to do to make SocketIO work with my NodeJS app on Google App Engine, I deployed the same application on a test server on Heroku and it works perfectly. Please I need help with this.

Hello, unfortunately App Engine Flexible does not support WebSockets. You should instead use Compute Engine or Container Engine in order to run your websocket application.

Hello, it is not possible to sign up for early access to Web Sockets on App Engine. A link to the signup form was posted on the feature request for a Web Sockets API.
