Antminers L3+ lost all boards. Cannot connect to cgminer

[iz25]

Guys,


I have 5 L3+ . Got all of them about 10 days ago.
Everything was fine, but all of a sudden , I see that all of them are unable to connect to all pool servers.
Network is working fine and network diagnostic is able to ping servers.
And I see X-es on all chips on all devices.
I have rebooted , shutdown and restarted all 5, and after that I am not able to see any hashboards at all and it cant connect to cgminer...
I use apw3++ PSU, connected to 30AMP PDU, 240V.
The temperature was notmal,  no chip got hotter than 55, and boards were about 43


can they all die simultaneously ?

errors in log:

Code:

Dec  6 09:09:30 (none) local0.err cgminer[22928]: Get [1]Temp Data Failed!

Any ideas?

Yeah I woke up and noticed my two L3+ were down because Nicehash has issues at the moment.

I switched them to Prohashing for now.
