Mining efficiency zero

I have an antminerl3+ Suddenly mining efficiency falls to zero. Miner status screen shows normal. I am seeing the following in my kernel log.

Have you flashed the firmware before? I'm trying to read up on this and all i can find is that people flashed their L3+ incorrectly, for instance, once guy accidenly flashed his L3+ with D3 firmware

Do any of the hashboards show up (or are any missing) when you access your miner?



Should show 4, just like above.

Mining efficeincy takes 2 hours to get a good reading.
I think they rebooted the server.

Until its hit a 2 hour mark that reading will likely be off for a while.
FYI...it is normal for you to have 0 mining efficiency when the pool isn't up for you to connect to and mine on.
