On a Windows 2016 Server (1607) we're currently facing quite strange TCP Connection Reset issues on TLS1.2 Client Hello on a port with port-proxy (netsh interface portproxy add v4tov4 ...); sometimes the Client Hello leads to an Connection Reset error, some times the connection is properly established.
Screenshots (links due to reputation) below;
the connection is coming from 10.86.81.0/24, accessing 196.168.112.38:7447 (port-proxy), which is forwarded to 172.16.13.70:443.
Is there a way to further debug what is happening here?
