I have an AWS EC2 instance. The instance has Bitcoin Core (Testnet) node and a LND node. It is working fine. Now, I want to install another LND on a different EC2 instance, but connect it to the same Bitcoin Core node. I tried opening the RPC ports and modified the LND config file of the new node with rpchost pointing to the first node. When I launch LND on the new node, it hangs after opening the wallet. Any ideas as how to configure this?
bitcoin.conf:
testnet=1
server=1
txindex=1
rpcallowip=0.0.0.0/0
rpcbind=127.0.0.1
