Broadcast process failed unexpectedly

[dugan_sharp_b9zB]

Tried to send a test transaction (within the same offline wallet), since I have not done any transactions in some time. All went smoothly until the final broadcast stage, where I got the "Broadcast process failed unexpectedly" pop up. Based on other instances of this issue that I searched for, I'll mention

• the blockchain was definitely synced up to the latest block
• Bitcoin Core is 0.13.2, Armory is 0.95.1, OS is Debian stable
• offline signing machine is 32 bit and uses Armory 0.93.2 (seems to sign successfully)
• I've set Armory to not start bitcoind automatically; rather, I always start bitcoin-qt first, and then start Armory
• I've sent successfully sent transactions from this set up before, with Core 0.12.? and Armory 0.94.1 (probably), so I'm thinking maybe I didn't do the update process properly

Thanks for any help. Here is the relevant bit of armorylog.txt (some stuff ###'d out or shortened with "..."):

Do a rescan and try again.

[dugan_sharp_b9zB]

Still the same "broadcast failed" after the rescan. I did the rescan only, so I will try the "rebuild and rescan" next and report back. Thank you.

Won't change anything.

In the broadcast dialog, you can copy the raw tx as hex. Grab that and try to broadcast it straight from Core, you'll get a error message giving you an idea as to why it's failing.

[dugan_sharp_b9zB]

Thanks for the help.

Short version: exported the raw hex transaction from Armory, sent via Bitcoin Core, transaction is confirmed and on the blockchain, so the broadcast failed for other (still unknown) reasons.

For anyone interested, here's how I exported the raw hex transaction. The starting point is that you already have the signed .tx file ready on your online computer. In Armory go to "Offline Transactions" > "Sign and/or Broadcast Transaction" then load the signed .tx file and choose "Copy Raw Tx (Hex)". The appropriate contents are copied to the clipboard (it's a long string of hexadecimal digits). Paste the clipboard contents into a text editor and save it, e.g., "raw_transaction.txt".

Close Armory and Bitcoin Core and start again on the command line (or anyhow just make sure you can access bitcoind on the command line):

Code:

bitcoind -daemon
RAW_TX=$(cat raw_transaction.txt)
bitcoin-cli sendrawtransaction $RAW_TX

In my case, the output of the last command was a valid transaction hash for a transaction that is now confirmed on the blockchain.

So my system is producing healthy signed transactions. I would guess the broadcast failure has something to do with how I've got Armory interacting with Bitcoin Core. I will continue to try to troubleshoot the broadcast failure, and report anything I learn. But I'm happy to know I can send through this method. Thanks again.

[droark]

Which version of Core are you running?

[dugan_sharp_b9zB]

Running 0.13.2

[JeBeL70]

Had the same issue initially, but restarted both Bitcoin Core (v0.13.2) and Armory (v0.95.1), and then transaction proceeded OK.

[Peg]

I also use both Bitcoin Core (v0.13.2) and Armory (v0.95.1)

I stuck at 0 confirmation.....and then double spending......

I sent bitcoin last week still pending...0 confirmation fee:0.0001btc. Then clear all unconfirmation also "rebuild and rescan" and sent some yesterday, then got double spending.  No idea how to solve this!!!

[goatpig]

You need to perform a CPFP, which Armory does not support atm.

[Peg]

Thank you for your advice . CPFP (Child Pays for Parent), don't know how to perform with armory 095.1. 

What is the minimum fee can get the confirmation of transaction? 

Does those unconfirmed transactions  ( https://blockchain.info/address/1KcvKB2zBdFPyMHMJUMjMAa182jPWiKseA ) need to clear?

I did clear all unconfirmed transaction  in armory. Can I send the bitcoin normally?

No CPFP in 0.95

What is the minimum fee can get the confirmation of transaction? 

Pick fee/byte option when sending, it will show you your nodes auto fee rate.

I did clear all unconfirmed transaction  in armory. Can I send the bitcoin normally?

That clears ZC from your DB, not the Bitcoin network. Nothing short of CPFP can help you.

[Peg]

Thank you goatpig!

No CPFP in 0.95 wait for 0.96

==================================================================================================
I want to delete my unconfirmed transactions from Blockchain.info?

Unconfirmed transaction means that your transaction is being broadcast through the network until some miner write it down into a block. If the unconfirmed transaction is not confirmed into the blockchain after some days, it is deleted from the network.

Nowadays, there is no easy way to delete your unconfirmed transaction. Unless you broadcast it again with a higher fee. In that case, the one that enters first into the blockchain (probably the one with higher fee) will automatically delete the other one from the unconfirmed pool (after a propagation delay).
===================================================================================================

That means I use same wallet to make a new transaction with enough fee to process, all unconfirmed transactions and double spending will be clear in the network. Am I right?

Doubt it.

No CPFP in 0.95 wait for 0.96

I didn't imply I'll do CPFP for 0.96.

Hello Goatpig,
Great to have you here.
Maybe you can help me with my previous post.
