lnd: Error when first launching LND with bitcoind

I’m launching lnd with the following command, and then create / unlock the wallet. After unlocking the wallet lnd stops. (i’ve xx-ed out user/pass/ip)

 ./lnd --bitcoin.active --bitcoin.node=bitcoind --bitcoind.rpcuser=xxxxxx --bitcoind.rpcpass=xxxxxxxxxx --externalip=xxx.xxx.xxx.xxx
