Mining rewards

I started NKN mining march 2021. It’s now been 10 months. In the first 5 months I received 9 mining rewards. In the last 5 month’s I’ve received 0 mining rewards. My node is telling me everything is fine with a green “mining” symbol. What’s up?

number of PERSIST_FINISHED nodes went from like 30,000 to 130,000 drastically reducing your number of rewards.
