Websockets and Adafruit Feather OpCode 11 - ruby

Question

My goal is to connect an Adafruit Feather (WiFi) to a Websocket Server running on my computer.
Server: EventMachine Simple Server Example
Clients: ArduinoHttpClient > SimpleWebsocketExample
My issues is that when I reset my Feather, I sometimes cannot reconnect. I have to wait a couple of minutes, a couple of extra resets, before I can reconnect. Turning on the debug flag on the server code, I see two patterns:
Successful connect

# :(
I have the Feather attempt reconnection in a while loop. I thought my issue might be something associated with timeout/throttling the data from very quick reconnection attempts, but alas it looks like this is not the case.
Thoughts on how to diagnose the issue? I'm eyeing that opcode as the potential culprit, but unsure as to whether to try and suppress it in the server side or figure out why its being placed there on the client side.
