Hello everyone.
On antminer S21+ there are 10+ percent of rejected shares, while on series 19 and below I see less than 0.5 percent.
What could be the reason for this?
This a common occurrence or just something you noticed now? Likely not something to be worried about but can check to see hardware errors and any other reported issue in your log. The S21 series have had their little run of issues, and finally is firmware is latest?
If this is the first time you noticed give them both a reboot and see if you get the same results.
