This likely needs to wait for #1657 to be merged first.

@william-xiang I have tested it and it's working great.

}

If you are happy with your testing, I am happy to merge.

@worksofliam I see you used the hostname for the testing. I guess with this PR #1657, when using the IP address and secure is enabled, the user will get an warning message about changing to use hostname. Do we still want to keep this message?

[worksofliam]

@william-xiang I can try creating the certificates with an IP address today as well. Let me post back when I've done that.

Just tested new certs, connected with an IP in secure mode and it works great!

Let's merge.
