I have recovered my wallet from an old data file using Bitcoin Core. The wallet has synchronized without issues. I have tried to send BTC to at least two exchanges and neither transaction has completed. After the first transaction (going to the Coinbase Wallet) I waited 10 days and then tried increasing the transaction fee - no change. The returned stats code says "Status: 0/unconfirmed, not in memory pool, abandoned."
I then cancelled that send and tried sending to Kraken and it's still processing after six days. The status code for this one says "Status: 0/unconfirmed, not in memory pool?
Any ideas? Am I just SOL?
