Pi-Hole blocked domains minus 2


I have been running Pi-Hole successfully now for some time, but recently noticed the blocked domain list was minus 2 domains.

I saved and updated the gravity list of domains but still the system does not reflect the captured domains.

I have otherwise been unable to find anything helpful in understanding this problem.

Current installation:

Pi-hole Version v4.4 (Update available!)
Web Interface Version v4.3.3 (Update available!)
FTL Version vDev (development, vDev-7dea0f0)

n.b. I updated the balena-pihole release today using https://github.com/klutchell/balena-pihole and the “Deploy with Balena” method but the UI still displays the old version. A separate issue, but thought to mention it here.


Hey @n1md4, can you confirm that you are using Raspberry Pi Zero? If so, this platform is not officially supported by the Pi-Hole docker images and the -2 Domains in blocklist is a known issue.

Follow this issue for more details:

If an official Pi-Hole image is ever released for armhf we will add it to the balena-pihole repo as soon as possible!

I actually linked an old PR which has a lot of comments, but here’s the issue I meant to include: https://github.com/pi-hole/docker-pi-hole/issues/245

Yes, actually I am using the Zero, so that’s a shame. Thanks for letting me know.

Thank you for the assistance. The information from those links is outside my understanding. Is this likely to be resolved any time soon?

Is it possible to run Docker on a RPI0 and the run a Docker container on that? That’s to say, is this a Docker or Balena problem?

Hi @n1md4, I would say this is pi-hole problem not Docker or Balena.

In this Github issue https://github.com/pi-hole/docker-pi-hole/pull/506, there are people using the pihole/pihole:v4.4-armel for pi zero without any problem, if you are fine with Pi-hole 4 then you can give it a try.

Thanks @nghiant2710 in the end I multi-contained on a Pi3, and it runs perfectly.
