Configuration error for nodeAddr 'rpcalpha.tzbeta.net'

[nicosampler]

If I configure Granary with this:

"nodeAddr": "rpcalpha.tzbeta.net",
"nodeRpcPort": "443",

I'm not able to run commands anymore, all of them fail with this message:

$ granary client - rpc get /protocols
Warning:
  Failed to acquire the protocol version from the node
  Rpc request failed:
     - meth: GET
     - uri: http://granary-tezos-node-sandbox:8732/chains/main/blocks/head/protocols
     - error: Unable to connect to the node: "resolution failed: name resolution failed"

Error:
  Rpc request failed:
     - meth: GET
     - uri: http://granary-tezos-node-sandbox:8732/describe/protocols?recurse=no
     - error: Unable to connect to the node: "resolution failed: name resolution failed"

Even passing the flag --tls or -S from https://tezos.gitlab.io/master/api/cli-commands.html.

• Running the command directly from tezos-client, it works if the flag -S is provided.

This is the example working in tezos-client
