Sorry if this is not the correct place for this, but I think I have my 2nd failed R-Box. I bought 6 a few weeks ago and had a lot of trouble getting them set up. I tried BFGMiner, CGMiner and now I'm running the R-Box software on a R-Pi. I was only able to get them stable after a lot of troubleshooting and taking one offline about a week ago. The remaining 5 were running fine until tonight when another one seems to be giving me the same issues.
If someone from R-Box can PM me and give me some help fixing or replacing these.
