Looks like it just hasn't fully propagated... I have the transaction in my node, and the fee isn't terrible, so no idea why it isn't showing on b.info... Possibly there is a conflicting transaction in the b.info mempool that already spends the UTXO being used... ie. a possible "Double Spend" attempt?
Have tried accelerating your transaction, hopefully it'll get a confirmation shortly.
my btc transactions are not able to be found on the above links neither, what should I do?
