Just got my apollo II full node. The tape on the microsd card I understand for transport but I think it creates issues with card seating in the slot. I had boot issues until I removed the tape, re seated the card, then the apollo booted fine.
But here is my issue. Miner started and works fine. The node started loading and loading fast connected to ethernet with 10 connections. then about 25% in it crashed. now I get the error message "Warning: Connection refused. Your node is not running."
Quick update. While loading the node and blockchain. I get the random same error message "connection refused: node not running" Each time I hit start node and the node connects and continues on. Any reason why it keeps crashing? This time the log only shows the last successful data block completed.
I hate to sound like the person on the typical "help line" . . . but honestly, it sounds like you may just need to reformat the node drive via the web based UI with the Format Node SSD selection under SETTINGS / EXTRA. Give it enough time to format (there's no status bar). Once formatted you can either start node (if it doesn't start automatically) or reboot. Personally, I prefer a fresh reboot. That should do it (unless the actual drive has went bad or maybe it's not seated all the way).
That's my best guess. Sorry.
Cheers!
