[FIXED] One.one.one.one can't find home-assistant.io: Server failed

Hi,

Since today I cannot access home-assistant.io anymore, it has been working really well before :worried:

My network provider is vodafone PT

Below are my diagnostic data

I can resolve it via 1.1.1.1, however, via a different PoP

nslookup home-assistant.io 1.1.1.1
Server:  one.one.one.one
Address:  1.1.1.1

Non-authoritative answer:
Name:    home-assistant.io

          104.26.5.238
          172.67.68.90
          104.26.4.238

Now, is working for me too!! I don’t know if someone seen the post and fixed the issue, or just pure coincidence :smiley:

It may have been an isolated issue regarding LIS data center, because I also tested at the same time from a server located in the UK and the dns for home-assistant.io was resolving fine there.

I had the same issue a couple of years ago

Must be a bug on Cloudflare’s end still, maybe @adspedia can look into it again?

Regardless, thanks for the extremely detailed bug report!
