Hi,
I think that the client called [resourceServer] establishes the correct 
connection with a server located on 52.43.245.161:8443. This server does 
not send any more data and the connection will be terminated, that's all.
It looks like:
openssl s_client -connect 52.43.245.161:8443

CONNECTED(00000003)
depth=2 C = US, O = GeoTrust Inc., OU = (c) 2008 GeoTrust Inc. - For 
authorized use only, CN = GeoTrust Primary Certification Authority - G3
