Hi guys,

For some reason the DYNU is not updating saying that there's Bad Authentication:

[15/01/2020 10:47:59 AM] Checking if IP update required.
[15/01/2020 10:48:02 AM] IP address update initiated.
[15/01/2020 10:48:03 AM] [Bad Authentication]
[15/01/2020 10:48:03 AM] Current IPv4 Address: None
[15/01/2020 10:48:03 AM] Current IPv6 Address: None

I've signed out and back in, but the issue still persists each time I try to update.

Any ideas?

Do you have a group associated with the domain name? If so you can put the group name in the 'Location' field in the client. That should resolve your issue.
