To start with, let's make sure that port 8172 is actually bound. To do that, run netstat -aon | findstr :8172 from a command prompt. You should get something that looks like this:
netstat -aon | findstr :8172
TCP 0.0.0.0:8172 0.0.0.0:0 LISTENING 4
TCP [::]:8172 [::]:0 LISTENING
4
If you get this, then nothing is listening on that port.

C:\Users\terri_2.TD-LAPTOP>
The next thing will be to turn off Windows Firewall to ensure that it is not blocking the connection. You should turn it back on after testing. If you are able to connect with the firewall turned off, then it is an issue with the rule. If you are not able
to connect with it turned off, then you will need to move to your perimeter firewall (either your router if this is your home network or your companies firewall) and have port 8172 opened there.
