Connect to local besu client failed: Connection Refused

[meijiesky]

Describe the bug
We are comparing BlockScout and Beaconchain explorers and want to use one of them in our project.
We have a private local network with one/four besu clients and we want to use explorers to show blocks/txs in the network. I modified the config file and the shell script because I don't need to connect to testnet/mainnet. However, it was very hard to get it working with Beacon. If so, we have to choose BlockScout then.

To Reproduce
Steps to reproduce the behavior:

1. comment out code below "Spin up a local ethereum testnet" in main.star
2. modify provision-explorer-config.sh to set CL_PORT and EL_PORT to my besu rpc port "8545"
3. (hacky) modify provision-explorer-config.sh to set clConfigPath to empty and name to mainnet because running the script failed due to the failure to call eth/v1/config/spec for besu client

chain:
  clConfigPath: ''
  name: 'mainnet'
  elConfigPath: 'local-deployment/elconfig.json'

5. kurtosis run --enclave my-testnet .
6. bash provision-explorer-config.sh
7. docker compose up

Expected behavior
All containers running properly.

Screenshots
All containers exited and the logs are as follows.
