These seem to indicate that the local (client to proxy) TCP connection
was closed gracefully at TCP level, but it shouldn't have been.
Do you get any logging or console output from the proxy?
Does it have tracing or debug options you can use?
Or can you put tcpdump or ssldump or similar on it?
Can you see with netstat or similar that a connection exists
1) before CONNECT: from client to proxy
2) after CONNECT: client-proxy also proxy-server
3) after SSL_connect: NOT client-proxy? what about proxy-server?
