Runtime error with bitcoind backend

torkelrogstad commented 6 years ago

I've been trying out the new bitcoind backend mode, and I've been having some issues.

After starting bitcoind (and ensuring it syncs completely before doing anything else), lnd gives me this errror:

2018-01-18 11:02:01.643 [INF] LTND: Version 0.3.0-alpha

My lnd.conf looks like this:

[Application Options]
no-macaroons=true
noencryptwallet=true

[Bitcoin]
bitcoin.active=true
bitcoin.testnet=true
bitcoin.node=bitcoind

[bitcoind]
bitcoind.rpcuser=xxx
bitcoind.rpcpass=xxx

My bitcoin.conf looks like this:

testnet=1
rpcuser=xxx
rpcpassword=xxx
server=1
txindex=1
zmqpubrawblock=tcp://127.0.0.1:29000
zmqpubrawtx=tcp://127.0.0.1:29000

I'm running Ubuntu 17.10, with Go version 1.9.2.

We have a fix for this coming up as another user has also reported the same issue. In the meantime, please make sure you specify either all or none of bitcoind.rpcuser, bitcoind.rpcpass, and bitcoind.zmqpath under the [Bitcoind] section in lnd.conf. You can use bitcoind.zmqpath=tcp://127.0.0.1:29000.
