Error: The node is not in a connected state

Hello everybody,

I have difficulty getting NBXplorer to connect to a running bitcoind instance running in Docker. I setup NBXplorer and bitcoind in docker instances, both running on the same machine.

Bitcoind is setup with rpc username and password. When I use the standard docker-compose file, I get the message fail: Configuration: BTC: Error connecting to RPC server Response status code does not indicate success: 401 (Unauthorized). Which makes sense of course. I tried to add username and password directly to the docker-compose file via: NBXPLORER_BTCRPCURL: http://username:password@bitcoind:18443/ Which gave the same result.

I then added the information to the settings.config file like this: btc.rpc.user=username btc.rpc.password=password

The result is this error message:

The notification The node is not in a connected state is not clear to me as I can connect via ElectrumX with no problem.

Any idea what I might do wrong here? Your help is much appreciated!

Thank you for that tip! In the end it was so easy…

port needed to be specifically defined for regtest. I changed port=39388 to regtest.port=39388 and then it worked. Note, I previously used port=3000 but that resulted in a different error resulting from a script running within the container.

Thanks a lot for your support!

Please try

bitcoin-cli -rpcuser=user -rpcpassword=pass help

This has probably nothing to do with NBXplorer, but how you set up your bitcoin node.

Hello i seem to have the same issue https://github.com/dgarage/NBXplorer/issues/310 , and the rpc credentials seem correct:

 litecoin-cli -rpcuser=xxx -rpcpassword=yyy getbalance
