2545	"TLS ""Close Notify"" warning"	Hay1tsme@…		"I have an old application that uses TLS 1.0 that I was attempting to proxy to a web app via NGINX. Unfortunately, NGINX seems to be causing a ""short read"", according to the app, and wireshark shows the app sending a ""close notify"" warning. Doing a janky setup without NGINX does not cause these warnings to show. I have tried switching web frameworks, and even languages entirely (twisted python -> rust actix -> rust rocket) but the same warning persists. The warning also shows when running NGINX on a raspberry pi. The configuration is listed below.
