Can you share your batch file for bminer on flypool? I cant get it to work on flypool for some reason. Also, what cards are you using?
Here ya go:
bminer -no-timestamps -uri stratum://t1dU7Gve41A3b4mxL7a3oVAnBLsF9kMgDgA.eleusis2:10000@us1-zcash.flypool.org:3333
Obviously change the ZEC address and worker name. This fixes difficulty at 10000, too (theoretically, anyway).
