Good day, i have a lot of power outages at the moment, i need to connect to my home machine to restart my miner when the power is restored, all machines have been loaded to my TV account and appear online/offline as i power them on and off, the machine at my home has not been loaded with TV yet and i was testing it at my office on two machines, the connection occurs quickly and the window appears on the right of the remote screen BUT the machine i am connecting from opens the remote window but it is just black, no icons or any options at all
