4001 is a communication error (can be followed by 9000 and game close), so these people back in June wont be the only ones to get it., being in the IT field you should recognize this.

if lots have it at once then net issue or server issue is more likely, one person would point more to a local issue and AV and Firewall is the best places to check for launcher.exe and swtor.exe
