Netflix dns problem

[Abhut 0]

Since a few days I have a problem getting netflix.com resolved via 10.4.0.1 (other domains work just fine:

C:\>nslookup netflix.com 10.4.0.1
Server:  UnKnown
Address:  10.4.0.1

DNS request timed out.
    timeout was 2 seconds.
DNS request timed out.
    timeout was 2 seconds.
*** Request to UnKnown timed-out

C:\>nslookup google.com 10.4.0.1
Server:  UnKnown
Address:  10.4.0.1

Non-authoritative answer:
Name:    google.com
Addresses:  2a00:1450:4001:81d::200e
          172.217.22.110

If I try it using the pushed DNS server it works - however since I'm using a pihole and can't update the upstream DNS server dynamically I would ideally like just use the 10.4.0.1 one.
Is there something I'm missing or could be doing wrong?

Cannot reproduce. Which server are you using?

Sorry for the missing info, this happens on all german servers except Ogma, Errei, Intercrus, Mersarthim, Veritate, Tucana and Serpens. Now that I checked that it seems this is more of a bug report instead of a I need help post. Sorry for not realizing it might have something to do with specific servers, I use a german-only servers config and apparently was only having bad luck to always get connected to servers that did not work.

Connected to Cervantes. The result is.. peculiar. On second thought, though, netflix.com is being redirected through one of the US rerouting servers because Netflix is good with blocking VPNs.
