So I have a client that connects from inside a docker container (although I don't believe that part is relevant). After the client finishes connecting, the connection holds for about a second before the client reconnects. I can't find to find anyone with a similar issue so I am wondering if I have a config issue or if anyone knows of a similar issue.
