Cannot connect to RPC endpoint

Check if your local nodeos is running by visiting the following URL in your browser:

curl http://localhost:8888/v1/chain/get_info

If you are trying to connect a remote nodeos API endpoint, try to visit the API endpoint with the following suffix:

http://API_ENDPOINT:PORT/v1/chain/get_info

Replace API_ENDPOINT and PORT with your remote nodeos API endpoint detail
