Web server - Server 2012 R2, IIS 8, ASP.NET application
Firewall Cisco 5515
Un-Managed HP switches, No vlaning
Client has been using Curl from the outside to hit our application.
No one else should be using the server.
Using wireshark i can see, If I have TLS 1.2 enabled, every time they hit the server at the end there is a RST
If i disable TLS 1.2 there is no packet RST and everything looks fine.
What could be causing this?
Please let me know if you need anymore info.
