The high rejection rate of mining machines usually has the following situations:
1. Poor network, slow network speed
The mining machine connects to the mining pool for mining. The mining pool regularly distributes jobs to the mining machine, and the mining machine then submits the share to the mining pool. This process involves a large amount of data transmission. The network situation has a direct impact on the mining machine's computing power and rejection rate.
2.The temperature of the miner is too high
The excessive temperature of the mining machine will also affect the computing power and rejection rate of the mining machine, especially in the hot summer. Different mining machines have different adaptations to the maximum temperature. Usually, the temperature below 90-100 is relatively normal. The specific needs to be confirmed according to different models.
Some miners may have a generally high rejection rate due to firmware issues. In similar situations, you can consult the mining machine manufacturer.
