https socket.io + pm2 cluster = Connection closed before receiving a handshake response

[geekyme]

My chat server is running an express + socket.io setup. They listen on https port 8443. I do not have an nginx to route to 8443 and that is ok.

I use pm2 to run a cluster mode on 2 CPUs.

Now when a client attempts to connect to my chat server, he gets

WebSocket connection to 'wss://chat.abctest.com:8443/socket.io/?EIO=3&transport=websocket&sid=f3bvw3rY1cRf1YkCAAAA' failed: Connection closed before receiving a handshake response

There is nothing peculiar in the logs that indicates this failure.

Now when I run pm2 in fork mode, the client no longer sees that error.

Please help.
