How to troubleshoot quickly when the miner is offline?

Many miners will encounter the situation that the miner is offline during the mining process, and there are not many reasons for the miner to be offline. Therefore, according to why the miner dropped, we divided it into physical problems and software problems.

Physical problems

1. Power failure

Note: Abnormal power failure may cause system file damage. If the equipment is expensive, it is recommended to purchase UPS.

Detection method: If all electrical appliances are turned off, there must be a power outage.

2. The network cable is damaged

Note: This specifically refers to the network cable connecting the router to the mining machine; if the network cable between the optical modem and the router fails, the router's WIFI cannot access the Internet.

Detection method:  Connect the miner to the monitor to see if the QR code is displayed normally. If the system prompts "insert boot media in select" when booting, the hard disk is damaged.

2. The network card of the miner is damaged.
