This error means either one of two things:
1 There is no server listening to that port on the host PC.
2 The firewall blocks that port.
Solutions:
1 Make sure the appropiate server is running on the host.
2 Make sure the firewall allows incoming traffic through that port.

How can I check all those things?

: How can I check all those things?
:
1: Depends on which port. I'm not going to list which server uses one of the 65536 available ports. See www.google.com for that.
2: Read the help files/manual/documentation that comes with your firewall. I cannot describe the procedure for each and every firewall in existance.
