Qnap LXD Container with Pihole not working after update

Expected Behaviour:

-operating system Ubuntu Kinetic on LXD Container
-hardware]_ Qnap TS-230

Actual Behaviour:

Pihole was running fine until 2 days before that I updated to the latest version. DNS service not running and FTL is down. I made a clean installation of Ubuntu and Debian also and the problem is still exists. I have an old LXC Container with Ubuntu 18 (so I can't update) with older versions of pihole and is running fine. Today I updated to the version that released today and the problem still exists.
