I hope someone can help me. A couple of hours ago i made an transaction from my bitcoin core wallet to my kraken wallet. Unfortunately i put in the wrong miners fee (way to low). I found this topic and followed the steps of starting bitcoin core with -walletbroadcast=0 and then i was able to abandon the transaction. When i did this i got my bitcoins back in my core wallet.

I then send my bitcoins again to my kraken account, this time i used dynamic fee and put the slider all the way to the right and also increased the amount of btc to transfer just because i wanted to transfer more btc. The status of the transaction showed "offlline". i figured out this was because i started core with "-walletbroadcast=0". So i restarted core without "-walletbroadcast=0" and then the status showed "0/unconfirmed, in mempool". When i search up the transactionid in blockchain.info it cant find the transaction. So i am wondering what went wrong and how can i fix this?

ps i also tried the rebroadcast the transaction by getting the getrawtransaction and using blockchain.info/pushtx, this gave me the message: Validation Error: Error #-26: 258: txn-mempool-conflict

The original transactionid with the way to low miners fee is: e57f73265506025cf486d4d51c959b5ede9117dddba6bc8a6764875ae4edd6b4
The new transactionid is: 6d50925ccae27615480b0a9b11f7be3391f2805a09b343d93d0adcd7ffeb601b

Thanks in advance!
