Hi, I am trying to connect to my LND node on my LunaNode server, but am experiencing some difficulties

I am getting this error when I try to display my node info using npm run dev

this is the error: E1215 21:18:57.672958000 140735946343296 ssl_transport_security.cc:643] Could not load any root certificate.

I am pretty sure my readonly macaroon and tls.cert are properly base64 encoded I am not sure, however if my LND_GRPC_URL is correctly set...

my .env looks like this:

` PORT=3000

LND_GRPC_URL="[myExternalipv4address]:11009" LND_MACAROON="M...U2" LND_TLS_CERT="T....09" ` any help greatly appreciated!

UPDATE: The problem was that I used the readonly macaroon string from my BTCPay server settings. I now properly base64 encoded my readonly.macaroon-file and tls.cert and now I no longer get this specific error message.

I now get the error "Error: 14 UNAVAILABLE: failed to connect to all addresses" I guess I'm now one step closer to victory! ^^

@johandegrieck I am trying to get this to connect to a raspiblitz node. I'm getting the same "Error: 14 UNAVAILABLE: failed to connect to all addresses" in the terminal console and "api.ts:55 WebSocket connection to 'ws://localhost:3001/api/posts' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED" in the browser console. Any help appreciated. Thanks.
