I want to run my LND instance (again) and have some trouble with connecting to bitcoin's ZMQ.

Here is what I do:

$ bitcoin-cli getblockcount
575704

$ lnd --bitcoin.mainnet --bitcoin.active --debuglevel=debug --bitcoin.node=bitcoind --bitcoind.rpcuser=tepo --bitcoind.rpcpass=**** --bitcoind.zmqpubrawblock=tcp://127.0.0.1:28332 --bitcoind.zmqpubrawtx=8332

after unlocking lnd wallet I get:

I believe that your configs are ok, but when you launch lnd with the command like flags, you overwrite one parameter to a broken value.

Specifically, I am talking about the flag --bitcoind.zmqpubrawtx=8332, which should be --bitcoind.zmqpubrawtx=127.0.0.1:28333 instead.

  • you're right! bash history not always helps...

    In my case, I have domain names configured, not IP adresses. So, it helped to add tcp:// before the domain name, like --bitcoind.zmqpubrawtx=tcp://mydomain.com:28333.
