What is the normal Rejection Rate? What do I do if it is too high?

The Rejection Rate is usually within 2%. If it goes over 2%, please check whether the miner's local network is stable.

The rejection counts of the mining machines refer to the number of shares submitted by the mining machines to the mining pool server and rejected by the mining pool for not meeting the requirements. The rejection rate is the proportion of the share submitted by the mining machines to the share rejected by the mining pool to all the shares submitted by the mining machines received by the mining pool.

The rejection rate within 2% is normal. If the rejection rate of mining machines suddenly increases, it may be caused by unstable network connection, which is usually an occasional phenomenon. However, if the rejection rate is too high for a long time, packet loss and delay may be caused by network communication problems, when network cables and network conditions should be checked.

Over-temperature of mining machines will also affect the hashrate and rejection rate of mining machines, especially in hot summer. Different mining machines have different adaptability to the maximum temperature, and usually the temperature below 90-100 is relatively normal. Specific needs should be confirmed according to different models, and you can check the relevant values from the official website of mining machine manufacturer.
