Cannot start a second lnd on my local machine in regtest

[Luca-Fischer]

Hello,

I am running a bitcoin node in regtest on macOS and try to run mulitple lnd nodes to test out the lightning network.
Here is my bitcoin.conf:
`
rpcuser=bitcoinrpc
rpcpassword=OaKWn2TLfJBq-Lvjssq-...

zmqpubrawblock=tcp://127.0.0.1:28332
zmqpubrawtx=tcp://127.0.0.1:28333

estimatesmartfee=3

txindex=1

regtest=1

daemon=1
`

Bitcoin starts with bitcoind.

Then I run my first lnd with lnd1. Here is the .bash_profile and lnd.conf:
`
export LND_DIR="$HOME/Library/Application\ Support/lnd"
export MACAROONPATH="$LND_DIR/data/chain/bitcoin/regtest/admin.macaroon"

alias lnd1="lnd --lnddir=$LND_DIR";
alias lncli1="lncli --lnddir=$LND_DIR --network regtest --macaroonpath $MACAROONPATH --tlscertpath $LND_DIR/tls.cert"

export LND_DIR_2="$HOME/Library/Application\ Support/lnd2"
export MACAROONPATH_2="$LND_DIR_2/data/chain/bitcoin/regtest/admin.macaroon"

alias lnd2="lnd --lnddir=$LND_DIR_2";
alias lncli2="lncli --lnddir=$LND_DIR_2 --network regtest --macaroonpath $MACAROONPATH_2 --tlscertpath $LND_DIR_2/tls.cert"
`

lnd.conf for lnd1:
`
[Application Options]
debuglevel=info
maxpendingchannels=5
alias=regtest-lnd
color=#123456
restlisten=0.0.0.0:8081
rpclisten=0.0.0.0:10009
tlsextraip=0.0.0.0

[Bitcoin]
bitcoin.active=1
bitcoin.regtest=1
bitcoin.node=bitcoind

[Bitcoind]
bitcoind.rpcuser=bitcoinrpc
bitcoind.rpcpass=OaKWn2TLfJBq-Lvjssq-...
bitcoind.zmqpubrawblock=tcp://127.0.0.1:28332
bitcoind.zmqpubrawtx=tcp://127.0.0.1:28333
`

Everything works, I can create a wallet with lncli1 create and so on.
With the second lnd2 I have trouble.
My lnd.conf for lnd2:
`
[Application Options]
debuglevel=info
maxpendingchannels=5
alias=regtest-lnd-sender
color=#654321
restlisten=0.0.0.0:8083
rpclisten=0.0.0.0:10011
tlsextraip=0.0.0.0

[Bitcoin]
bitcoin.active=1
bitcoin.regtest=1
bitcoin.node=bitcoind

[Bitcoind]
bitcoind.rpcuser=bitcoinrpc
bitcoind.rpcpass=OaKWn2TLfJBq-Lvjssq-...
bitcoind.zmqpubrawblock=tcp://127.0.0.1:28334
bitcoind.zmqpubrawtx=tcp://127.0.0.1:28335
`

I can run the command lncli2 create but after entering a password, n, 'enter' I get:

[lncli] unable to generate seed: rpc error: code = Unavailable desc = connection error: desc = "transport: authentication handshake failed: tls: failed to verify certificate: x509: certificate signed by unknown authority (possibly because of \"x509: ECDSA verification failure\" while trying to verify candidate authority certificate \"MBP-von-MyName.fritz.box\")"

When I do not run lnd1 but run lnd2 and try to create a wallet I get a different error:

[lncli] unable to generate seed: rpc error: code = Unavailable desc = connection error: desc = "transport: Error while dialing dial tcp 127.0.0.1:10009: connect: connection refused"

When I test the network connection I get:

nc -v localhost 10011 nc: connectx to localhost port 10011 (tcp) failed: Connection refused Connection to localhost port 10011 [tcp/*] succeeded!

And for this:

nc -v localhost 10009 nc: connectx to localhost port 10009 (tcp) failed: Connection refused nc: connectx to localhost port 10009 (tcp) failed: Connection refused

But the first lnd does start.

I am completely clueless.
Does anyone can help?

x509: ECDSA verification failure...

This means you're not specifying the correct TLS certificate to use in your lncli2 command. Make sure you point --lnddir to the correct directory.

127.0.0.1:10009: connect: connection refused

That means lnd isn't responding on that port. Because lnd2 is running on 10011 as you configured in the config. So whenever you're trying to talk to lnd2, use lncli --rpcserver localhost:10011 --lnddir <see_comment_above>.

Basically your problem is that when using lncli you correctly need to address each node by its data directory and port it is running on.
