I am running my own bitcoin fork with three nodes from last 3 months and i was able to mine and i mined 780k blocks but back from few days i stopped mining the blocks. But now i want to start the mining again but it giving me some error in pooler/cpuminer as 500 server error.
So from research i have got to know it is happening because of no block generated from so many days so i am trying to generate new block with bitcoin-cli generatetoaddress 1 but it wait for sometime and retuns empty array [] because the difficult level is high as 2.8***.
So can somebody suggest me some solution?
