@Sir William

I'm still not able to connect on windows.  I registered with suprnova.cc and created a worker.  I am using the worker login and worker password. I have tried flipping the switch to both positions. Do i have a bad unit???

 [2017-06-27 17:47:06] Most likely you have input the wrong URL, forgotten to add a port, or have not set up workers
