harvester_1 | socket.gaierror: [Errno -2] Name or service not known

[Ethereumx]

In order to use the explorer with a localsubstrate node I have changed the docker compose to indicate its address :+1: SUBSTRATE_RPC_URL=ws://127.0.0.1:9944 and I've removed the container substrate-node

But after running the explorer I am getting the following error continuously :

Keep in mind that localhost means the Docker container of the harvester and not the host machine where you probably run the Substrate node. You might want to use host.docker.internal:9944

This conversation seems to have ended. I'm closing this issue.
