The retransmissions probably mean some program on your machine is repeatedly trying to make a connection to the server on port 5555; the packet is an "initial SYN", which is the first packet in a TCP connection attempt, and it's probably being reported as a "(suspected) retransmission" because there were previous similar connection attempts.
Are you seeing any packets coming back from 54.72.75.192, such as one where "Flags:" includes both SYN and ACK (that's a response to an "initial SYN")?
