mod_proxy made a new backend connection and was presumably able to
perform an SSL handshake.  But when it went to read the response, with
no delay from when the conn was established, the connection had
already been torn down by the other side.

I don't know what IHS handshaked with here, or where the likely TCP
RST comes from, but if it's not your appserver it's something in front
of it.

You'll need to scrutinize a packet capture from around the same time.
The mod_proxy_http.c(1144): error shows you the ephemeral port used by
mod_proxy and should let you zoom in directly to the failing
connection.  If the RST really comes in shortly after the encrypted
HTTP request is sent, then you're debugging the wrong system
