Hi,

This connection, https://[my-ip]/admin, will be encrypted - note the “https” at the beginning. The OpenVPN 1-Click option ships with what is known as a “self-signed” SSL certificate which most browsers do not trust. This is why the “page might not be trusted or secure” warning comes up when you try to visit a site with a self-signed cert. The data will still be encrypted, though.

If this was a commerce site or something you’d want to be highly accessible by more than yourself then you’d probably want to take a look at LetsEncrypt and setting up a free, “signed” SSL cert.

If this is just you accessing the admin and you trust that it is your Droplet, then there’s no technical need to change what you have.

Hope this helps, if you have any other questions or feedback please let us know.
