Flask-SocketIO: Server hangs intermittently immediately after WS upgrade
First of all, thanks so much for everything you do Miguel. your Pycon presentations are great, and I really appreciate your willingness to share your knowledge.
I’m using Flask-SocketIO with a fairly straight forward configuration, but the socket is hanging intermittently while trying to upgrade. I’ve tried multiple versions of socket.io, and I get the same behavior. It seems to happen to approximately 1 out of 5 connections.
Below is the server log, you can see @ 17:35:56 that the socket hangs for 1 minute before re-connecting.

@miguelgrinberg,
I’m in the middle of a 24hour hackathon at work, so I stopped trying to test, and started trying to workaround it.
It does happen a lot more when reloading, but also sometimes happens on a fresh load from a new browser window.
I should have a complete app in about 8 hours, I’ll try to upload it then.
