Connection issues with addons and integrations

since 2 days I have connection issues with addons and integrations. I have no network problems since I can reach all websites by my browser and can login to HA by internal connection. I also can update HA of Addons. Restarted HA several times, restarted HA DNS.

I think it has something to do with the DNS. In the terminal I can ping 8.8.8.8 but ping google.com gives bad address

my logfile:

What is your DNS server set to here:

Settings → System → Netwok → Configure Network Interfaces → [your network adaptor] → IPv4

IPv4

IP-adres: 192.168.178.33/24

Gateway: 192.168.178.1

Methode: auto

Naamservers: 192.168.178.33

IPv6

IP-adres: fe80::a3a8:d633:adfc:5b99/64

Methode: auto

I changed the name server manually to 1.1.1.1 and then it works.
But I have adguard running on HA and all my devices works with 192.168.178.33 I do not understand why home assistant is not working on this point.
