Curl error 7 specifically means that curl failed to establish a connection with the server at the specified address and port. In this case, it's trying to connect to localhost (127.0.0.1) on port 443, which is the standard port for HTTPS. This often suggests a problem with the server not listening on that port, a network issue, or a firewall blocking the connection.
