Hmm, is 192.168.178.5 the DNS-server for your network, or are you using your fritzbox as dns-provider?
The output should look like this for the fqdn (fully qualified domain name)âŠ
nslookup fritz.box
Server: 192.168.333.1
Address: 192.168.333.1#53
Name: fritz.box
Address: 192.168.178.1
dig fritz.box
...

âŠor like this for the reverse lookup.
nslookup 192.168.178.1
1.178.168.192.in-addr.arpa name = fritz.box.
dig -x 192.168.178.1 # <- you have to set -x for a reverse lookup!

Using dig to querry for an ip instead of an fqdn (without the -x) will cause the dns server to treat the ip like an fqdn he canât resolve, querry his root-servers and fail. But it shows that in your case 192.168.178.5 is the dns-server your host is using for dns-resolution.
In any case 192.168.178.5 does not have any dns informaton for your network it seems.
So you should either set the correct dns-server via dhcp or directly via /etc/resolv.conf, or make sure the dns-server has the appropriate information.
If 192.168.178.5 is the host itself, systemd-resolved still is active and not using the dns-server for your networkâŠ
