Why this SSL connection ends abruptly

I am trying to make an HTTPS POST request. The connection ends abruptly at the very beginning. I took the following capture with Wireshark. 192.168.0.33 is my client attempting to connect to the server. 192.185.47.210 is the server.

I suspect the problem is with packet 57, because upon receiving this packet, client initiates a disconnect of the TCP connection. Packet 57 looks like

Other info:

The client is a C# program running on Windows XP. The call is made by the WebRequest (https://msdn.microsoft.com/en-us/library/system.net.webrequest%28v=vs.110%29.aspx) class. The server is on shared hosting (Hostgator) with dedicated IP and an SSL certificate from COMODO.

Question

Can anyone help me understand why receiving packet 57 is causing the client to disconnect?
