I have a new website and its DNS entry (thetunegame.com) is now 10 days old, so it should have propagated properly.
I've had over 200 people from several countries accessing it with no issues, however there are 4 people, all from Greece (although this could be a sample bias), who can't access it. One sent me this screenshot:
I understand this means their system can't find a DNS entry. I'm not an expert and this is not my own system, so I'm limited as to what I can do, however I have ascertained that:
- Changing to Google DNS servers (and doing ipconfig /flushdns) does not solve it
- Changing network does solve it
- Not all 4 people are on the same network/ISP (therefore it's not an issue with a particular ISP)
- Changing browser does not solve it (in case it was a Chrome caching issue)
My set up:
- Google-registered domain, pointing to Cloudflare DNS
- Cloudflare has DNSSEC enabled (in case that matters)
Things I've tried:
- Asking the people who have this issue to do the things described above
- Test the DNS resolves OK for me and for servers around the world via several online tools (it does)
- Checked the DNSSEC settings between Google and Cloudflare are consistent
I'm completely stuck! I can't understand how 4 people (not on the same network) can't see it, even when trying via Google DNS servers.
I have no idea what else to test, in case it's something wrong with my setup.
Is there a way of confirming that my setup is correct?
And if it is, what else can I ask these people to try?
