Tuaris and Haudini,
after I installed the older firmware and replaced the ethernet cable, the message "socket Connect failed" also appeared. However, after 2 or 3 minutes it disappeared and my S9 connected to the pools. I have NiceHash as my 1st pool, and slush as my 2nd pool.
I did changed the firmware however i got connected to antpool after 30 mins.....
however the issue i am facing now the temperature field is displaying ' - ' ....
