You may receive the "Can't Enable Remote Connections to JTAG Server" error if your computer's firewall program or your IT department has blocked port 1309.
Another sign that port 1309 may be blocked is that when you try to enable remote connections the settings will not be saved and revert back to default settings.
Enable port 1309 on your computer or firewall program or speak to your IT department to make sure they are not blocking port 1309.
Note: Administrator access may be needed to enable this port.
