I upgraded to Windows 10 and can still connect to Android and iOS without issue. Make sure breakout server.exe is included in your firewall Inbound Rules. If it is and still doesn’t work I would suspect the issue may be in Android. Version 4.1 may be too old (websockets may not have been supported yet). Android 5.0 should work for sure though unless if you have a non-Nexus device and the manufacturer messed with how sockets work in the OS.
