Most likely your -datadir parameter is incorrect or it's corrupted which causes bitcoind to download block from beginning.

Please share your debug.log file so we could find the cause.

I think my -datadir is correct, because debit.log sit inside correct directory.

Here is the first 100 rows from my debug.log
