The URL and port for a connection is requested from our server at the time you make a connection, and will often change.
To make the connection point persistent, there is a way to accomplish that today, although it requires the use of a client side daemon. This is demonstrated in the sample scripts shown here:
You use the service's UID along with a login token (retrieved from our cloud REST interface) to start the client side daemon and then that connection becomes available on 127.0.0.1:33000 (for example). The script sshw.sh is hard coded for SSH but it can be modified to just return a URL instead of making the SSH connection for you. The webw.sh script likewise will return a connection for an http endpoint.
Another possibility if you don't mind doing a little programming is to use our REST API documented at docs.remot3.it to grab the dynamic connection info. The typical sequence is:
/user/login gives you a login token to use with the next 2 calls
/device/list/all pulls down JSON formatted list of all of your services
/device/connect, given the UID and token, will return a dynamic connection URL:port to use
