So I just recently started mining, and for the first month everything went fine. 100% uptime basically. Now every 24 hours or so my miner will show as offline on simplemining.net and be offline in dwarfpool, but the actual computer is still running fine and has the green light on so I assume its still connected to the internet. I've been trying to change the default information through ssh, but I'm still trying to figure it out. Does it sound like I'm being hacked?
