Antminer L3+ Hashboard Not Detected

Hi Guys,

I got a new Antminer L3+ about a month ago and I installed Hiveon Firmware on the machine successfully. After a few hours of working normally on all 4 hashing boards, the overview panel shows the following message:

“number of x=4 of chain 3 has exceeded threshold”

And hashing board No.3 is not detected anymore. It is only after I restart the machine that all the hashboards show up again. It has happened 4-5 times in the past 24 hours. Could anyone help me regarding the possible error that has been occuring and possible ways to correct it?!

Firstly, run the AutoTune feature from control panel and check the results from. AutoTune log page.

Probably your hashboard damaged and it need to repair.
