I’m seeing this error:
cardano-node: FatalError {fatalErrorMessage = “Cardano.Node.Run.createTracers.readTopologyFile: Is your topology file formatted correctly? The port and valency fields should be numerical. Error in $: empty”}
I suspect it’s because the topology format doesn’t include valency.
The Topology file from your link above has only one node so not sure if that’s enough for a relay node.
