I start up my game, but i can't see nor connect to any server. it happened for the past two days.
This can be antivirus related remove re-add exceptions for launcher.exe and swtor.exe
Norton's - set the exceptions to allow not just auto
ESET - disable protocol filtering
Kaspersky - disable scan secure connections
ensure if you are running compat modes that launcher.exe and swtor.exe are identical , try setting both to XPSP3 if the above doesn't work.
