Hello, i just got a Antminer S19j pro +
and for most of the time it runs normal. But sometimes the Hashrate drops for 15-30min and all Hashboards are receiving thousands of HWs, after that the Miner just continues and no more HWs are happening.
This is what the Log shows:
2023-06-09 11:58:17 30m avg rate is 121857.63 in 28 mins
2023-06-09 12:03:54 Version num 64

2023-06-09 12:03:54 freq = 660, percent = 90, hcn = 3971, timeout = 2287

2023-06-09 12:13:19 chain 2 hash rate 21491.00 low in 15 mins

Does anyone know how to fix it?

Best regards.
