I made a transaction a few days ago, but the fee was to low so it doesn't get confirmed. So I want to give the transaction a higher fee. But when I resend the transaction I get this error:
258: txn-mempool-conflict
I restarted my server.
I tried leaving the output the same but added an input.
I tried changing the output to an higher fee and left the input the same.
I tried the abandontransaction command but that returns Transaction not eligible for abandonment.
But the error is still there. How can I resend my transaction so it will get confirmed?
