Trouble: HiveOS shows 300 MH/s, but HiveOn shows 0 MH/s

The subject. I use HiveOs for mining and I was very satisfy till last next days. Sometimes ago, Pool statistics began shows only 0.000, but when I checked it in my admin panel on the.HiveOS I saw 300 MH/s? What the problem? What I have done:

  1. I checked ETH wallet number. It was correct.
  2. I tried to use other pool - Nanopool. It was the same situation - ZERO again!

What can I do the next to solve the problem?
