no connection to master server

[DUAL-CORE]

yes, i try logging into my tcadmin, and it says Could not communicate with the master server.. I tried restarting the service, restarting the pc, and still nothing.

Try stopping the TCAMonitor Service and start TCAdmin in console mode. That should tell you where the problem is.

I just had the same issue, make sure your MySQL service is actually running. Mine wasn't and that was the reason for the error.
