It seems to be bac, I found in the antminer web interface that diff was 1024 instead of 512 when it didn't work.
Yep, working now. So strange...
It may have been a temporary error of siamining pool.
Is someone mining with luxor mining pool
https://mining.luxor.tech?. Do you know how it works and the rewards it gives?.
Regards!.
No, it's not a pool issue, it has happened to A3s since day one. It's always all the pools.
