Unable to access gov.uk

Any gov.uk website doesn’t work when connected to the pihole. Requests are not blocked but never receive a reply. Pihole says “No reply received”.

What could be causing this ?

Do you have DNSSEC enabled? If so, is the time/date on your Pi correct for your local time? Accurate time is required for DNSSEC authentication to succeed.

What upstream DNS server are you using? Have you tried changing this to a different upstream DNS server?

There could also be a problem with the gov.uk nameserver.

https://dnsviz.net/d/gov.uk/dnssec/

There is a certain misconfiguration in the DNSSEC realm of gov.uk: it does not respond at all over TCP and sometimes queries get lost over UDP. Furthermore, some mandatory records are even missing. Interestingly, when you run, e.g. a local unbound instance, you may be able to navigate around these issues as the settings recommended by Pi-hole still manage to get the necessary records and finish validation.

Necessary to continue on this question: Which upstream server(s) are you using?

Is your ISP Virgin Media and are you using their Hub 5 router?
That router breaks DNSSEC TCP replies. It also fails to resolve .tv domains.
The answer is to use the router in modem mode and provide your own router or add a config to your pihole to divert queries for the failing domains.
This was discussed in Unable to get to gov.uk domain when using PiHole & Unbound - #7 by i7andy

Same here. With me it happened when Virgin Media changed my IP address.
I now have a file /etc/dnsmasq.d/99-my-settings.conf in which I have added:
server=/**.gov.uk/1.0.0.1
server=/*.tv/1.0.0.1
and then restarted dns
(There should be a single asterisk on that first line )

I worked through this problem with technical support at Janet, gov.uk's provider. Their initial reply was:

Please be advised, and rest assured, that DNSSec for .gov.uk is not failing and there are no issues with any of the nameservers that serve the zone. The perceived issue that you have reported is a direct result of DDoS mitigation attempts undertaken by the security systems that protect the Verizon nameserver that you reference. The automated tool that you reference generates a number of repeated and rapidly successive probes which are being mitigated before reaching the nameserver, hence the appearance of a failure of the nameserver itself to respond to some queries. If you examine a combination of results from the tool, you can see that they’re all related to query timeouts and that the specific queries that are timing out vary over successive attempts. This, ultimately, has no impact on genuine, operational DNS lookups aimed towards the nameserver.

Putting my router into modem mode and using an old router that I flashed with openwrt proved the problem is with Virgin Media's router.

Interesting, yes I do use VM and their Hub 5. I’ll give this a go. Thanks!

I still don't think this is accurate, third-party DNSSEC debugging tools show several issues, too, see e.g. the one @jfb linked above:

  • gov.uk zone: The server(s) were not responsive to queries over TCP. (192.76.144.14, 2001:600:1c0:e001::35:6)
  • gov.uk/AAAA: No response was received from the server over UDP (tried 12 times). (192.76.144.14, 2001:600:1c0:e001::35:6, UDP_-NOEDNS)
  • gov.uk/DNSKEY: No response was received from the server over UDP (tried 12 times). (192.76.144.14, 2001:600:1c0:e001::35:6, UDP_-EDNS0_4096_D_KN, UDP-NOEDNS)
  • gov.uk/DNSKEY: No response was received from the server over UDP (tried 4 times). (192.76.144.14, 2001:600:1c0:e001::35:6, UDP_-_EDNS0_512_D_KN)
  • gov.uk/NSEC3PARAM: No response was received from the server over UDP (tried 12 times). (192.76.144.14, UDP_-NOEDNS)
  • gov.uk/SOA: No response was received from the server over TCP (tried 3 times). (192.76.144.14, 2001:600:1c0:e001::35:6, TCP_-_EDNS0_4096_D_N)
  • gov.uk/SOA: No response was received from the server over UDP (tried 12 times). (192.76.144.14, 2001:600:1c0:e001::35:6, UDP_-NOEDNS)

Their support explain that because of the nature of DNSViz's multiple queries, their antiDDOS protection kicks in.
They suggested:

I do think that you’re on the right track though, in the sense that there’s a commonality in terms of the size / type of query responses that are failing.

One thing I’ve noticed is that when, say, querying Google’s DNS on 8.8.8.8 for “gov.uk dnskey”, the response is sent in a single UDP packet - whereas the responses from the authoritative servers are truncated using TCP. I’m wondering if the TCP response is causing an issue somewhere, perhaps. Some queries you could try to help determine this:

If you have a firewall that fronts your Internet connection, it would be worth running a packet capture on the WAN interface whilst running both working and non-working queries. You can then analyse the pcap file in Wireshark, or similar, and verify exactly what response you’re seeing from the nameservers. Some routers may also have this level of functionality if you don’t have a hardware firewall in place. If the responses look good from the WAN interface, then repeat the capture on the LAN facing interface and finally on the interface of the LAN device running the query to help pinpoint the cause. Of course, if you’re not seeing a response on the WAN interface at all, then further investigations by your ISP may be required.

At this point I decided I was working above my pay grade. If I put Virgin's Hub 5 router into modem mode and use another router (I used OpenWrt) then I end up on a different IP address range and DNSSEC works. It is either the router or the address range. I tried cloning the router's MAC address to get the same IP address but that didn't give me an IP address.

My guess would have gone into the direction of MTU but as long as there is a viable workaround :wink:

And calling blocking of 12 of current can be called "antiDDos" or is just too radical is on them...

I have added that into my config file, but it still does not seem to be working.

root@ubuntu:/etc/dnsmasq.d# cat 99-my-settings.conf
server=/*.gov.uk/1.0.0.1
root@ubuntu:/etc/dnsmasq.d#

Note: I do not have DNSSEC enabled.

Did you enable this setting?

I did not. I now have, but still not working. The query log now shows it as:

I bet you cannot access https://www.turnon.tv/ either.
I have these commented out for the day when I have to use my Hub 5 as a router

 #server=/*.torproject.org/1.0.0.1
 #server=/*.ncbi.nlm.nih.gov/1.0.0.1
 #server=/*.infoblox.com/1.0.0.1
 #server=/*.gov.uk/1.0.0.1
 #server=/*.tv/1.0.0.1

It was the slow growth in exceptions that forced me to put my Hub 5 into modem mode.
It might be worth rebooting to see if your exception starts working.
Virgin Media support showed no interest in my problem.

Tom, login to the Virgin Media Community and have a look at

Sorry VM customers only.

Someone there posted

Hub 5 Router mode, current reported issues:

  1. Wi-Fi & DHCP Fail when both SSIDs are changed. ( in the Wizard and in the Menu )
  2. DHCP Fails with multiple DHCP devices.
  3. DHCP Reserved IP list fails to accept entries.
  4. DNS All queries are being intercepted by the Hub 5.
  5. DNS Queries for AWS hosts time out with both VM DNS & Public DNS.
    6. DNS DNSSEC queries fail.
  6. Port Forwarding may not work.
  7. RTSP stream / VRChat crashes & reboots Hub 5.
  8. Wi-Fi 6 / 802.11ax Fails to be visible to many 2.4GHz only devices.
  9. (Suspected) A laptop connected via 5GHz Wi-Fi may be unable to access a printer connected by 2.4GHz. May also mean mobile Phone on 5GHz is unable to detect / manage IoT on 2.4GHz.

Weirdly, I can access .tv domains, including the one you provided.

I have my Hub 5 in Router mode as do not have another router (well, I do but that's in another part of the house).

I have tried rebooting the Pi after adding those settings but does not work.

Does that mean this simply won't work using the Hub 5 in router mode?

So you do not have DNSSEC enabled. Have you installed unbound?

If you get the same response then your 99-my-settings.conf is wrong or not being read.
If you get no response try a different dns server such as 8.8.8.8

Can you post the output from the delv utility, it's more useful when DNSSEC is involved.

You can add some flags to the delv command, like +mtrace that will be quite verbose in the steps taken. I'll add that here:

I'm on VM I had this issue with Pihole and Unbound, to resolve this issue I had to do this (found this fix on a reddit thread):

Edit Unbound Config
sudo nano -w /etc/unbound/unbound.conf.d/pi-hole.conf

Add following to bottom line of unbound config
domain-insecure: "gov.uk"

e.g.:

Ensure privacy of local IP ranges

private-address: XXX.XXX.XXX.XXX
private-address: XXX.XXX.XXX.XXX
private-address: XXX.XXX.XXX.XXX
private-address: XXX.XXX.XXX.XXX
domain-insecure: "gov.uk"

NOTE: Also had to disable DNSSEC in Pihole gui.
