I've tried making this request locally to the remote server using
graph create --node https://index.myurl.tld my-project/my-subgraph
as well as trying on the server using ./shell cli
graph create --node http://127.0.0.1 my-project/my-subgraph
Doing both I'm getting the following error
✖ HTTP error creating the subgraph: ENOTFOUND
I've also tried this with adding the :8020 port to the end of the URL with the same outcome.
