Node has stopped running. Appears to be due to storage filling up since it's only a 500gb drive. If I'm not mistaken, the solution is to simply obtain a larger capacity sd card and insert into the bottom of the node unit, yes?
Simplest solution is to enable bitcoind pruning (which is limiting number of blocks to certain value, basically discarding old blocks, so hard drive don't overspill). But Futurebit has not got around to support their users properly - this is nowhere to be found in the settings. You are left out, you either have to configure pruning yourself via SSH, in bitcoind config files, or purchase 1TB NVMe drive, for around 70 USD last time I checked.
