Transaction does not exists

[imawriter]

Hello there i had made this transaction
https://blockchain.info/tx/42617b56cba1ec75f80e62e0af4f7e30cdb61fbf3a3a1a9ac0a640c37c6dd2f0
Later i realised that i payed less fee.So i thought i should accelerate this using viabtc but when i tried to do so viabtc says that transaction does not exist.Dont know what does that mean

I've seen this problem before in at least two other threads and if I recall, there were these explanations offered:

1. Your tx fee "contains dust"... I couldn't confirm this as your tx also does not appear on blocktrail.
2. Your tx is from another unconfirmed tx, in which case you have to wait for the former one to confirm before this one can.
3. Your tx needs to be rebroadcasted. Just leave your wallet open to do this.

That's all I can remember.

I've seen this code: 258: txn-mempool-conflict before... IIRC, the last time, it was because one of the inputs of the transaction was already used for a different transaction that was already sitting in my mempool (aka, double spend)

So what can i do now

It doesn't seem like blockchain.info has a double spent transaction in it's mempool, however https://live.blockcypher.com/btc/tx/42617b56cba1ec75f80e62e0af4f7e30cdb61fbf3a3a1a9ac0a640c37c6dd2f0/ says that there are only a limited number of nodes that have this transaction in their mempool.

What *could* have happened is that one of the inputs for this transaction was already used in a different transaction a couple days ago... This previous transaction remained unconfirmed, dropped from the mempool of most nodes (like blockchain.info) but not from others.
If this is the case, the first transaction *should* be dropped by most nodes in a couple of days, and you *should* be able to re-broadcast this one.

Once again: this is only a theory!

Yes okk i pretty much understood.Any ways thanks alot

The double spend seems to have come from address: 1738xnZVyBF2ToFe2cihuLPvmVgSkCanfw

specifically the transactions:

https://blockchain.info/tx/0f8197251408b3c6913eb8812a63469db37566b237329b671bf33088feb285ad

This will prevent you from using ViaBTC and/or trying to get help directly from a miner as they generally don't like dealing with double spends.

If no-one rebroadcasts these, they will hopefully fall out of the mempool in the next day or so... try keeping your wallet offline (to help prevent rebroadcasting) for a day and keep checking the block explorers to see if they drop out.
