I changed DNS to CloudFlare but my website is not running

[shopvietworld]

Hi,

I changed DNS to cloudflare as the instruction, but my website is not working

My website is groupbuyexpert.com

You can visit my website now and it says Error 1016 with this message

Then I try to login cloudflare from my hosting, but it says No or invalid host_key.

I searched some another simillar topic for error 1016, but still cannot fix it

Is that what you have in Cloudflare DNS for ‘www’?

You should also have an “A” record for groupbuyexpert.com with the same IP address.

Glad to hear it works. It’s best to pick one canonical URL: with the www, or without. And then forward the unwanted one over to the canonical, like this:
