Hi
I am having an issue with the cloud when providing website site address, is there a way i can connect to ip + port.
I'm not entirely clear what you're asking, but if you're asking whether you can connect to JupyterLab by opening your browser to an IP address rather than a custom domain, the answer is no because SSL requires a domain name. If you can't connect to your custom domain, run docker-compose logs houston and see if there was an error when Let's Encrypt tried to install the SSL cert.
If you're asking about SSH access to the cloud server, you can use docker-machine ssh quantrocket to do that.
