Low hash rate in Binance Pool

Anybody knows why my hash rate in the Binance Pool has fall (220 MH/s), buy in HiveOs says I’m mining at 295.

The estimate earn at this hour (from 19:00 yesterday to 16:00 today) would be at least 0.0045 ETH, but it is at 0.0035. What is happening?

Update, the hash rate in Binance says now 145 MH, but in HiveIs says 295.

I have the same problem, is there a solution?
