To those suffering and unable to see their hashboards, consider changing your ethernet cable. Thanks to woodgiins
https://bitcointalk.org/index.php?topic=2274299.20I was using Ugreen right angled ethernet cable and I changed it to a normal one and guess wat, my hashboard appeared.
This happened on two occasions on 2 different antminers. I am surprised.. Try it perhaps?
Before
These were the problems before on 2 different miners and all 3 hashboard work fine now
For the first pic, I updated firmware as well
This has worked for woodgins as well.
