No accepted shares Issue

Have been mining other coins fine with my rigs running HiveOS.

Today i tried several hours to setup and mine Grin, but it just would not work.

Rigs are running 1080ti and 1070 cards

Tried using bminer, grin-miner, grin-gold etc; but all of them connect to the stratum server, show mining hashrate for each card; show several attempts like 80; but accepted 0, rejected 0.

Any help on the above please

Pardon my ignorance…

Are you pool mining or mining on your own?
