I've been trying to follow the tutorial at https://developers.libra.org/docs/my-first-transaction
But I get the error
Not able to connect to validator at ac.testnet.libra.org:80, error RpcFailure(RpcStatus { status: Unavailable, details: Some("Trying to connect an http1.x server") })
when running ./scripts/cli/start_cli_testnet.sh
Has anyone else gotten this issue? I'm not sure why it wouldn't be available.
