"Connection was reset"

Can sometimes mean a php crash. Without seeing the exact files it's hard to guess if and why this is happening.

Make sure to check the error_log, type: php --info | grep error to see what file it's being logged to (if you are on linux/unix).

My guess is a stray break; statement somewhere see this answer for a possible cause: https://stackoverflow.com/a/20036720/988324

You would find some trace of this in your error logs though. If you can provide this I might be able to help more.
