I just got my Apollo unboxed and set up, and am running into an error after configuring the miner, it says its unable to connect to port 4028 (which I gather is the stats API port for bfgminer). The dashboard is blank except for the ECONNREFUSED error. The bfgminer process does appear to be running, however.
That usually happens when there is no internet connection to miner. Is the yellow LED flashing? If your already Poking around Syslog do sudo screen -dr miner that will bring up Bfgminer.
