I need help for know what want say this phrase, by 'bitcoin core' debug file.
here :
"addresses found from DNS seeds"
the number of address (upper), can say, the number of address with have funds ? or not ?
In this case, addresses refers to IP address/.onion link of other Bitcoin full node. There's no correlation between this debug message and your wallet.dat file.
my old file,
was one wallet.dat bitcoin
can't open On bitcoin core !
Did Bitcoin Core show any error/warning message when it tried to open your wallet.dat file?
