Talktalk and Cloudflare

Masterfrodo13 — Tue, 04 Oct 2022 18:13:14 GMT

Yesterday I migrated my website and email to Cloudflare DNS servers. Since then I have been unable to access either my website or my emails when at home, using Talktalk. I can access them on my phone, using 4G, and I can access them both away from home on other wifi's.

So what's going on? I have switched off the router at home for 30mins, with the hope that Talktalk would start a new ISP session, but still no luck.

My website is www.pr4photos.co.uk if anyone would like to see if they can access it on their Talktalk wifi.

Yes I can see that Website from my Talktalk wifi.

Thank you. I've been told it's probably the DNS that needs flushing by Talktalk. And that switching off the router for 1/2hr should do it. It didn't. So will probably switch it later and leave it off overnight, and hopefully that will solve the issue.

Have you tried flushing the DNS cache of the device you are using? On Windows ipconfig /flushdns.

Yes, I have done a DNS flush of my mac. It has to be to do with the router DNS because I can use my iphone on 4G at home and it connects to the website and my email. And if I use the iphone at a friends house on their wifi, it works fine. But at home, if I connect my iphone to the wifi, I get the same result as the mac

Strange. I can't imagine the router preserving its DNS cache when powered off. It seems more likely Talktalk have multiple DNS servers and they are not all in sync.

Have you tried changing the router DNS settings to Cloudflare?

I wouldn't know how to. And surely that wouldn't be necessary

See above.

As a workaround for this evening, I have downloaded and installed a free VPN. The free version only works on one device, which is fine, as it's the mac I need working this evening. And it works. Website works, and emails work.

Am I right in thinking that Talktalk will refresh/flush it's DNS automatically? I will switch off my router and leave it switched off tonight anyway. And if it works tomorrow without the VPN, great

Morning,

I'd recommend powering down the router for a full 30 minutes as this will reset the current session. How are you getting on?

Thanks

Hi Michelle

I powered the router down for 8hrs, and have just switched it back on. Unfortunately the result is the same. I cannot access my website, or my emails. However, if I switch on the VPN, I can access both. I am out for the day, so will leave the router on, so you can do what you need to do. And I will switch my computer off, so nothing will be trying to access either my website or email from this ISP

Morning,

Ok thanks for trying this. Whilst DNS changes are usually quite quick would it be possible to give this another 24hrs to see if this updates. If there is still no change then could you run a wired ping and traceroute to the affected site please.

Thanks

Hi Michelle

Still nothing, unless I use a VPN

Morning,

I'm sorry to hear this. Did you manage to run a ping and trace route to the affected site? Do you also see a specific error message?

Thanks

Traceroute

There is something very odd going on. If I go to pr4photos.co.uk it displays what looks like your website but if I ping pr4photos.co.uk it comes back with an ip address of 95.179.193.212. If I put that in my browser I get this:

If I traceroute to pr4photos.co.uk I get this:

If I put stevensserver.com in my browser I get this:

So it seems like the server at 95.179.193.212 shows different pages depending on the url you use to access it, weird.

I must admit, I don't understand any of it
