What is this TCP error telling me?
I'm trying to connect to a game server using port 5555 but it's having issues and I'd like to find out what's causing the problem. I get TCP Retransmissions in Wireshark, but I don't know what they mean. I'm hoping someone here could give me a quick answer. Here is the data of the packet.
Thanks.

does report that it cannot open a connection to the host. I'm just not sure why.
