I use this tutorial for run BSC node:


But with web3 I get error:

Uncaught (in promise) Error: CONNECTION ERROR: Couldn't connect to node

My code:

const web3 = new Web3();
web3.setProvider(new Web3.providers.HttpProvider('http://my-ip:27147'));
  • Do you try other eth command ?

It seems like your node is not deployed. To save you some time, you can use the following code to check if the node is up and running.

curl -X POST "http://localhost:27147" \
  -H "Content-Type: application/json" \
  --data '{"method":"eth_syncing","params":[],"id":1,"jsonrpc":"2.0"}'
