How to open port:


If you receive a message "Your Internet connection is either very poor or is not processing UDP packets through port 6112" then it means that port 6112 is blocked. In most cases not only one port but all UDP traffic is blocked by your router device or a firewall on your computer.
Also this may be if you use a proxy like VPN connection that doesn't support UDP packets.

Note: Starcraft default port 6112 can be changed in the Windows registry
