Bro, provide your script ? 
This is a jlp kangaroo, with precalculated tame kangaroos.You can make them yourself. By running a kangaroo in the required range with the -m 3 parameter in a loop with a false public key. In this way you will accumulate a lot of DPs.
After that, you will only need wild kangaroos.
Bro,I talk about this scrypt:
" Most likely, the sha-256 hash is simply a hash of the text that contains instructions on how to correctly convert a public key to a range of 80 bits an so on (which will be available tomorrow)."
