Hey Everyone,
I have some strange behaviour.
Tuesday I updated my Pi-Hole to the latest Version (PI-HOLE V5.11.4 FTL V5.16.1 WEB INTERFACE V5.13)
(Note: to do so, I had to Upgrade the OS from Debian 9 to 10)
After this update, all Windows PCs refuse to resolve any hostname on my local Network.
Browsing the Web is working fine.
Also my other Devices (Linux Mint / LMDE 4 / Pi / etc.) don't have any issues.
I have tried some requests via PowerShell:
nslookup without DNS Server specification:
PS C:\Users\Cetheus\AppData\Roaming\eDEX-UI> nslookup fritz.box
DNS request timed out.
timeout was 2 seconds.
Server: UnKnown
Address: fe80::84b9:25b8:ffb3:6dbb
DNS request timed out.
timeout was 2 seconds.

nslookup against Pi-Hole:
PS C:\Users\Cetheus\AppData\Roaming\eDEX-UI> nslookup fritz.box pi.hole
Server: pi.hole
Address: 192.168.178.10
Name: fritz.box
Addresses: fd00::3ea6:2fff:fef5:5aa2
2a02:8108:8b40:bf64:3ea6:2fff:fef5:5aa2
192.168.1.1
ping Router via Hostname actually works (via IPv6):
PS C:\Users\Cetheus\AppData\Roaming\eDEX-UI> ping fritz.box
Ping wird ausgeführt für fritz.box [2a02:8108:8b40:bf64:3ea6:2fff:fef5:5aa2] mit 32 Bytes Daten:

The IP-Setup is as following:
192.168.178.1 Router (Fritz.Box)
192.168.178.10 Pi-Hole (Raspberry Pi 3)
192.168.178.21 Windows PC (Windows 10)
IP-Setup (via DHCP through the Router):
Standardgateway . . . . . . . . . : fe80::3ea6:2fff:fef5:5aa2%5
192.168.178.1
DHCP-Server . . . . . . . . . . . : 192.168.178.1
DHCPv6-IAID . . . . . . . . . . . : 74483138
DHCPv6-Client-DUID. . . . . . . . : 00-01-00-01-27-DC-39-C6-70-85-C2-89-F8-DC
DNS-Server . . . . . . . . . . . : fe80::84b9:25b8:ffb3:6dbb%5
192.168.178.10
fe80::84b9:25b8:ffb3:6dbb%5
Expected Behaviour:
Resolving the Hostnames of my local Network, with or without the FQDN
Actual Behaviour:
I can't resolve any local Hostname only on my Windows 10 Systems.
