The rejection rate of a mining pool pertains to the proportion of data that is rejected by the mining pool relative to the total amount of data sent by the mining machine. This rate arises when the data sent by the mining machine is deemed abnormal or fails to meet the mining pool’s requirements, leading the pool to reject the data and thereby increase the miner’s rejection rate.

However, if the hash rate of your miner remains unaffected, this parameter can generally be overlooked.

The main factor contributing to a high rejection rate is instability in the network. The data from the mining machine is sent to the mining pool server via three nodes:

  1. Local network: Issues here usually involve interference or loose network cables.
  2. Operator network: The issue usually lies in network node instability.
  3. Mining pool server: The server may be experiencing exceptions or errors.

Depending on different algorithms and hash rates, the miner sends data to the mining pool every few seconds or tens of seconds.

Please note that mining pools are generally able to assist with testing. Should you need any assistance or face any issues, don’t hesitate to get in touch with the customer service of the mining pool.
