Getting 404 for /socket-io/?EIO=3&transport=polling&t=NG2FwLh when netty-socketio server and tomcat run on same port

[sansingh]

I'm trying to configure a Sprint Boot REST app that uses port 8080 to also use SocketIOServer on port 8080.

if i use another port for SocketIOServer, it works fine.

if i use port 8080, i get a port in use error unless i set the following:

@Bean
public SocketIOServer socketIOServer() {
    com.corundumstudio.socketio.Configuration config =
            new com.corundumstudio.socketio.Configuration();
    config.setHostname(nwtNasaWebsocketServer);
    config.setPort(Integer.parseInt(nwtNasaWebsocketPortString));
    SocketConfig sockConfig = new SocketConfig();
    sockConfig.setReuseAddress(true);
    config.setSocketConfig(sockConfig);
    return new SocketIOServer(config);
}

but then when i try to connect from the socket io client, i get a 404 for below call:

http://localhost:8080/socket-io/?EIO=3&transport=polling&t=NG2FwLh

I see similar issue opened previously #545 but no solution hint has been provided. Could someone please help here?

Any solution for this issue? I want to run my REST endpoints and socketio server on same port

You may want to take a look at port unification in underlying netty server.
