If you are mining nicehash to Beam pools, be aware that NH has errors, it's a bug in the nicehash system.
You will see some warning message in the miner, but please check your valid shares at poolside... the nicehash system will show you 100% invalid shares, but it pool you will see the correct output of your miner.
This was discovered by the op of Sunpool and nicehash support have been a little less than helpful in their responses to this. If anyone needs help with this, pop in to the support links in my sig on discord or telegram.

happy to help where needed.
