"Dynamic DNS settings" show "No settings available for this device"

[LB4MI]

Hi,
there was a old topic already for this, but not sure if it is related as it was very old: https://www.remoterig.com/forum/index.php?topic=1553.0

However after coming back for a two week vacation, I found my radio/control RR box not finding DNS server anymore.

The "Status" page is showing: "DNS status" show "Error, failed to resolve xxxxxxxxxx.ddns.remoterig.com!"
The "Dynamic DNS settings" page is showing "No settings available for this device"

Anyone seen this before? I haven't touched the box since it last worked.
