Problem setting up Nabu Casa for Remote Access

[UniKyrn]

Ok, signed up for the trial with NC and got the URL to use remotely. To get the secret again, I removed and re-added the integration, then took a screenshot of the info.

I plug that into Leaf Spy though and the URL does not resolve ...

From the debug log saved to DropBox:

02/20/2022 14:40:03 41 510 100 0 URL = https://****64li4928mrkydv.ui.nabu.casa/api/leafspy/update, Error = java.net.UnknownHostException: Unable to resolve host "****64li4928mrkydv.ui.nabu.casa": No address associated with hostname
02/20/2022 15:16:38 06 025 0 0 URL = https://****64li4928mrkydv.ui.nabu.casa/api/leafspy/update, Error = java.net.UnknownHostException: Unable to resolve host "****64li4928mrkydv.ui.nabu.casa": No address associated with hostname

That URL looks odd to me, the domain name is weird. Is that what others are using? It comes from the Accounts page on NC for my account.
