Rejected share refers to the share that your miner failed to submit to the mining pool due to network fluctuations and other factors.
The rejection rate is the ratio of rejected shares to the total number of shares submitted by miners. And the lower the rejection rate, the more efficient the miner.
As long as the rejection rate is below 1%, it is normal. You can calculate the rejection rate as follows:
Rejection rate = (expired number + repetition number + other) / (received number + expired number + repetition number + other)
If the rejection rate is higher than 1%, it is recommended:
1. Shut down and restart the miner
If you have many miners on your mining farm, you can use the bulk tool APMinerTool to manage your miners.

2. Check the network
If the rejection rate of all miners connected to the same router or switch is abnormal, it is recommended to check the entire network and replace the router or switch for testing.
If the rejection rate of a particular miner is abnormal, it is recommended to replace the network cable and network cable connector to the miner.
