Again, all that can be determined is that your PC is not getting a response
to it query. There is no information to provide any clue as to whether the
PC or the server is at fault.
I would suggest packet capture. On a Windows system, I suggest wireshark.
The same for the server, if it is yours. If the server is Unix and you have
access to do so, just simple tcpdump will work well.
