Timeout with local http servers (Python, Ruby, Node) about espduino HOT 3 OPEN

I've continued doing everything I can to debug this. I've updated my SO thread (linked above) as I go. I think I may have narrowed it down considerably using mitmproxy and tcpdump to carefully inspect the packets going through (though most of it is way over my head). It seems that any time the HTTP response from my local server is getting split into 2 packets, I'm getting the timeout (and status code 0) on the espduino. Any time it's a single packet, it works fine.

I can use either nginx or mitmproxy with the exact same Flask app (or other local server), and without a single change to the code, it will work great and espduino gets 200 responses when used behind either reverse proxy (both of which appear to be sending the entire response in a single packet), and if I turn off the proxy, the same code appears to work on the server side but the espduino returns 0 and times out. The response packets getting split into 2 segments is the only difference I can tell, so it seems like esp_bridge might be choking on them. I don't really know how to verify that this is the problem, so I haven't started an issue there yet.

I'm way above my head here -- does anybody know enough about reassembling ICMP / TCP packets to help look through the esp_bridge code and see if there might be an issue there?

I think this may actually be an esp_bridge problem. See my issue there (linked in the reference above).
