Getting rejected shares on CryptoNight, CryptoNightV7, V8 or CryptoNightHeavy?

If you are using 3rd party miners (xmr-stak, cc-miner, xmr and cast-xmr ...), you might get rejected shares on different CryptoNight algorithms due to wrongly set parameters. The most common reason for rejected shares is not choosing the correct algorithm for mining the desired coin. Make sure you select the correct algorithm for the coin you want to mine! Also check the pool compatibility with the desired algorithm. There are no known issues with CryptoNight rejected shares when using the latest version of the NiceHash Miner Legacy.

For CryptoNightV8 please make sure you are using the following settings (xmr-stak; LOCATION: eu, usa, hk, jp, in, br):

           “wallet_address”: “BitcoinWalletAddress.WorkerName”,
           “rig_id”: “”,
           “pool_password”: “x”,
           “use_nicehash”: true,
           “use_tls”: false,
           “tls_fingerprint”: “”,
           “pool_weight”: 1
       }
   ],
   “currency”: “cryptonight_v8"

For CryptoNightV7 please make sure you are using the following settings (xmr-stak; LOCATION: eu, usa, hk, jp, in, br):
