Hi BitMaxz thank for your reply.
So for you the problem just come from a problem with the internet connection ?
Something is strange because the three other asic with the same hub, same pool adress and same worker name are working fine…
Yes, based on your current logs above. Can you try to check if that miner is set to DHCP/Static mode if it is set to Static switch it to DHCP to let the miner use a unique local IP sometimes if the miner is set to static IP and another the device uses the same IP the miner internet not work properly so switching it to DHCP can solve this problem.
If it didn't work try to disconnect all devices and only run this miner.
Also, would you mind telling us exactly what pool you are currently mining and what other ASIC miners you have?
Because if you are mining in Nicehash with this unit it won't mine unlike other ASIC miner like Antminer units doesn't have any issue mining on Nincehash. Avalon units usually have problems connecting to the Nicehash pool.
