Problem with claymore on 3 rigs of 4 in one day

Today morning i rebooted my farm rigs (4 pcs). And 3 of 4 dont give hashrate after it. Look at this.
I tried to upgrade hiveos, tried make firstrun -f and its not affected.
Now i try to reinstall hiveos on one of rigs, but i think, it will be not work again.

How did you solve this problem?
I have the same, only 1 of 7 works properly
