Problem is there is no comunication info with herominers. I found mail address but never got reply from them.
After some time i searched again. This time google gave me telegram contact. It was public channel i asked to enable the payments. After a minute i got private phone call from him.
Heavy english accents, worse than mine

I asked simple question: please enable my payments. Whats wrong if iwant to mine with 1 cpu? I thought pool were ment to be small miner gather together and mine. No point if they disable small shares.
Anyway i cant access that public channel anymore he blocked me.
My mistake i wasnt checking my account for a month.
Thats why im saying check your account every day or once per week
