but theres a chain not working,

Code:

driver-btm-c5.c:13421:bitmain_c5_init: Chain[J6] has 63 asic
driver-btm-c5.c:13421:bitmain_c5_init: Chain[J7] has 62 asic
driver-btm-c5.c:13421:bitmain_c5_init: Chain[J8] has 0 asic

You have two bad chains, only J6 is in perfect condition, J7 should/might work with a bit less hashrate, but J8 is dead, you could go ahead and do all the troubleshooting Phill recommended but my guess is that hashboard is dead. it's not uncommon for used miners, where did you buy it from?
