Yong TK

My Z9 miner is able to start up and run normal for like 1-2 min then it will appear to disconnect (notice via cmd ping) then stuck and show the below

"connect failed: connection refused" at overview , it will stuck at this state for forever.

after reboot it will be able to run for 1-2min and then disconnect again, what is wrong?

    Hello Yong TK

    For the issue of Socket connect failed, please check your firewall and you may need to manually add the miner to your router using the MAC address and the static IP address of the miner.
