I am trying to join a family member's world. We are both on PCs, one Windows 8.1 and one Windows 7. We both use Minecraft 1.8.8
My family member's PC firewall is open to Jave SE binary and to Minecraft on the Public network, which is how the household WiFi router is set up. My firewall is also open to same (Java, Minecraft), and network is also public.
My family member enters their local world, and opens it to LAN, so "Local game hosted on port 5xxxx" appears in chat. I open Minecraft, click Play Multiplayer, and it scans forever on my local network (we don't have an actual LAN, just share a WiFi router). So I do Direct Connect and enter IP:Port, where IP is from doing "ipconfig" on the hosting PC and using the IPv4 local IP (192.168.x.xx), and Port is the 5xxxx mentioned above.
When I join I get the following error:
java.net.ConnectException: Connection timed out:no further information:
Note that I can go to cmd window and ping either her local IP (192.168.x.x) or the external IP (found via WhatsMyIP.com) for her machine, and the ping yields an apparent success ("Reply from ...").
What else can I try to enable me to connect to the other computer?
