Description

While debugging issue https://github.com/abhinavsingh/proxy.py/issues/43 I ran into the following error page:

screen shot 2019-02-21 at 9 46 04 pm

which hinted towards a certain bug during communicating between vpnkit and proxy.py container. For some reason, client connections to proxy.py are closed soon after proxy.py has received the client request, resulting in a tight retry request loop. See my https://github.com/abhinavsingh/proxy.py/issues/43#issuecomment-465841635 for more debugging details.

Any ideas where things might be going wrong here?

Research direction

Start with the linked proxy.py issue #43 and the referenced comment for the available debugging details about vpnkit and the proxy.py container. Trace why client connections close after the request; done means identifying the communication failure and confirming that the retry loop no longer occurs.
