I explicitly set my allow list to
127.0.0.1/32and was surprised that with my server settings like that connections from the client would freeze indefinitely with no errors in the logs.Digging into the problem showed that when an IP is denied it just continues for the next connection leaving the old connection to just leak and never close.
This adds explicit close. It may be better to have handle function that make sure close is in a defer to prevent future issues but that is more refactoring here. Also adds some logging when a connection is denied so that it isn't silent.
