So, I'm sure this has been mentioned before, but this is how I fixed my multiplayer issues:
TL;DR:
Add a Firewall Exception for the GalaxyClient.exe file.
The long version:
1 - Find the executable for the Galaxy Client (mine was located at C:\Program Files (x86)\GalaxyClient). If you aren't sure, you can probably right-click shortcut on your desktop and Open File Location
2 - Add the executable to the Windows firewall exceptions: Start -> Control Panel -> Windows Firewall -> Allow an app or feature through Windows Firewall -> Click on "Change settings", click on "Allow another app...", click "Browse", browse to the location from step one. Click add, then enjoy your gaming.
