Hello. I’ve sent a month ago some ETC ( in 4 tranzactions ) to my ledger nano. I check it up and was on indeed on ledger. Now shows me 0. I check up the address on gastracker and is shows all the ETC but this address I can’t find it on my ledger. Help please ! Ledger ia updated before to 1.5.5. I’ve selecte ETC network ( both of them ) but nothing.
