Cloudflare doesn't work.

Question

Cloudflare doesn't work.

UnwaryCoin9457 35

Since some time last year, Cloudflare has never worked except once. It keeps resetting itself. How can I fix this? I read that I can try to clear DNS, but every method to access it seems to require the Windows button which I don't have on the Xbox. (I don't want to clear my cookies unless I have to, and I think I did at some point only for it to not work.)

I don't know what it means that Cloudflare "doesn't work" and you haven't explained it.

To choose a third-party DNS service like Cloudflare, instead of using your ISP's own DNS service, sign in to your router's administration console and look for the menu that deals with choosing a DNS provider. There you can enter Cloudflare's DNS addresses.

Whenever I visit a website with Cloudflare it endlessly resets, asking me to verify repeatedly.

Cloudflare needs to be setup as they (Cloudflare) described in the link I provided. If you tried to setup Cloudflare by some other method, please reverse what you did and follow Cloudflare's instructions.

When Cloudflare is setup correctly, do you still have a problem? If so, go back to using the DNS service from your ISP. If you're still having a problem, even with the DNS from your ISP, then your DNS service is not the source of the problem.

I'm confused. Is this for setting up Cloudflare myself or visiting a site that uses it?

If you're referring to the link above, that shows you how to replace your ISP's DNS service with Cloudflare's DNS service.

A DNS service is a telephone directory on the internet, only instead of telephone numbers it has URLs. When your web browser looks for a URL (like www.microsoft.com) it asks the DNS service to supply it with the numerical equivalent of that URL, since the internet works with numbers and not letters. Your browser then looks for that numerical address on the internet.

Most people simply use their ISP's own DNS service, but there are also third-party DNS services, like Cloudflare, Cisco, Google, Dyne, etc. that someone can choose, if they wish.

Unless the entire DNS service goes down - which does happen, but rarely - about the only thing that can go wrong with DNS is that the website provides the wrong numerical value to the DNS service for its URL. When that happens, your browser won't be able to find the website because it's looking for the wrong numerical URL. That's the website's problem to fix.

This is why I originally wrote: "... If you're still having a problem, even with the DNS from your ISP then your DNS service is not the source of the problem." In that case there's probably nothing wrong with Cloudflare itself. Either the website provided the wrong numerical URL to the DNS, or there's a problem with your network setup.

Cloudflare-based sites or DNS sometimes fail in Edge when there are local DNS or browser issues. On Xbox, options are limited, but these steps can help without using the Windows key:

Restart the console

Fully power down the Xbox (not just sleep/standby), wait 30 seconds, then start it again. This clears some cached network state that can affect Cloudflare.

Check the network by trying other browsers/devices

Use another device on the same network (phone/PC) and try the same Cloudflare sites.
- If they also fail, the issue is likely the router/ISP DNS.
- If they work elsewhere but not on Xbox, the problem is local to the console/Edge app.

Clear Edge browsing data on Xbox (Does not require a Windows key; done inside Edge.)

Open Microsoft Edge on Xbox.
Open the menu (the equivalent of Settings and more – usually the “…” button).
Go to History > Open history page.
Choose Delete browsing data.
Set Time range to All time.
Select at least Browsing history and Cached images and files.
Select Clear now. This targets cache and history; cookies can be left unchecked if avoiding sign-outs.

If still broken, clear all Edge data

Same path: Settings and more > History > Open history page > Delete browsing data.
Choose All time and select all boxes, then Clear now. This is more aggressive and may sign out of sites, but can fix persistent Cloudflare failures.

Check for network/DNS issues on the router/ISP Because Xbox cannot run ipconfig /flushdns, use the router instead:

Restart the modem and router (power off both for 30 seconds, then power on modem, wait, then router).
After they are fully online, test Cloudflare sites again in Edge on Xbox. If other devices also have trouble with Cloudflare, contact the ISP and mention DNS issues, or change DNS on the router to a stable provider.

If Edge itself is unstable On Windows, Edge can be repaired via Settings > Apps > Installed apps > Microsoft Edge > Modify > Repair. On Xbox, the equivalent is to:

Close Edge completely.
If possible, uninstall and reinstall Edge from Microsoft Store on Xbox. This refreshes the app without affecting the console OS.

If none of the above helps and only Cloudflare-backed sites fail while others work, the most likely causes are ISP DNS problems or router-level filtering that interferes with Cloudflare; these must be adjusted on the router or by the ISP, not on the Xbox itself.
