PageSpeed Insights can't fetch my site after setting up a CDN

[CaptainHustle]

I added Cloudfare CDN on my blog with the hopes that my site speed would improve but turns out it doesn't. I removed it, entered the old nameservers on namecheap and saved it. For some reason, google page speed insights can no longer fetch my site.

Lighthouse returned error: FAILED_DOCUMENT_REQUEST. Lighthouse was unable to reliably load the page you requested. Make sure you are testing the correct URL and that the server is properly responding to all requests. (Details: net::ERR_CONNECTION_FAILED)

Any idea what could be wrong?

If you can reach the site on your own, then Page Speed Insights probably cached the information related to reaching your domain. It's the same reason you can run Pingdom twice and get a much faster result on the second fetch. They're caching.

I'd try a different inner page URL and see if it forces it to refresh. If not, I'd wait 24 hours or longer and see if the problem resolves itself. If your visitors can reach your site then everything is fine.

When you update nameservers they can take upto 7 days to propagate throughout the world because of the TTL, time to live, settings - which tell computers, servers, nodes, to cache the settings for a certain period of time.

It’s why a week before you do a major website move you are suppose to set your TTL to 5 mins, letting servers know a move is imminent and you won’t have this 24 hour, 48 hour, or whatever delay.

Basically Google’s lightspeed servers are working off the old cached setting to cloudflare and you need to wait- probably upto a week.
