DNS not working after Windows startup

Help
1

Expected Behaviour:

  • Pi-hole Version: V5.17.1
  • Router: Fritz!Box 7590 (Fritz!OS Version: 7.56)
  • OS: Windows 10
    The Pi-hole's IP address is distributed as a DNS via DHCP.

When starting up Windows, I expect the DNS to work right away.

Actual Behaviour:

When I start up my PC (This occurred on multiple Windows PCs), it takes several minutes until I can access the internet. I'm able to ping the local IP address of the Pi-hole and can connect to my router's configuration interface (via IP) but my DNS requests cannot be resolved. After a few minutes, it just starts working. I never have any issues on my mobile devices (iOS, Android). When I manually configure another DNS server, it also works instantly. I'm not sure if this behaviour started after a Pi-hole update or a router update.

Hey @Elektrogott are you still seeing this behaviour? If so, you're welcome to post another debug log (they only exist for 2 days and are then purged). Looks like we keep missing each other's posts, that does happen now and again!

I checked again and the issue seems to be gone now. I tested this on two PCs with Windows 10. Maybe it was an OS thing that was patched. My router has updated to version 7.57 but I don't think this is the cause of the change as it was a security patch.

Thank you very much for your help though!
