Login issue - Licensing error

[burekas]

Why do I get this error while trying to login?
What should I need to do?

It has always worked fine until now, and there are no known changes.
There was an active server that was briefly suspended due to payment issues. it was restored, and then this happened.

Licensing error
Unable to reach licensing servers for license validation.

DNS lookup failed with error lookup licensing.directadmin.com on 8.8.8.8:53: dial udp 8.8.8.8:53: connect: network is unreachable.

Check if DNS is properly configured in the server and file /etc/resolv.conf has valid DNS servers configured.

DNS lookup from CLI can be checked with command:

dig +short licensing.directadmin.com
If DNS working properly please open a support ticket.
