Unable to connect the pool for a long time (more than 5 minutes)
after starting up (the miner lights up yellow for a long time, does
not turn green light, has no hashrate).

LED light of the miner is green), but it has no hashrate.
2、Possible cause

If the PC cannot be connected to the miner through the network, you
can try to restore the factory settings after confirming that the
network environment is normal, the network cable is firmly connected,
and the miner is started normally. The method of restoring factory
settings is shown in Appendix I.
•
Check the current firmware version of mining machinery, and it is
recommended to update it to the latest version with FMS. See Appendix
3 for the upgrade method.
•
Check the status of the hashboard .
•
Click log to view the working status as shown in the figure below. It
should be in work normally. If it is overheating shutdown, check the
