Why are you getting rejected shares?

There are four different types of rejects:

• Stale share: The share was submitted too late (probably because of the high latency or problems with connection). This is the only type of share that is expected to happen in small quantities thus it is considered normal.
• Share above target: There is a problem with your mining software that needs to be inspected or configured properly. It is also possible that the mining software is not compatible with NiceHash.
  • Some ASICs on Sha256AsicBoost and Scrypt algorithms might receive additional Target rejects due to not supporting XNSUB. Read more here.
    
• Duplicated share: The share was submitted more than once and indicates a bug in your mining software or incompatibility with NiceHash.
• Other: Any other type of rejected shares usually means a bug in your mining software.

How to check the type of rejected share?

NiceHash Rig Manager shows the detailed reason for rejected shares. Follow these steps to check rejected type:

1. Navigate to Rig Manager,
2. Open rig details by clicking on the rig name,
3. Scroll down and navigate to Mining History Stats graph,
4. Change Showing Stats for All Algorithms to the desired algorithm.

Graph display will change to algorithm details. You can remove the redundant information by deselecting the Accepted speed, Payrate, etc. at the bottom of the page.
