Yesterday, I set up CloudFlare. I changed the nameservers from Strato to the CF nameservers. Now my websites shows a 404-not found error. I’m not sure what to do now because my main income is through my website.
Unfortunately this seems to be a common issue with Strato. Their shared hosting plans do not have a static IP. This means that you would need to update the IP at Cloudflare every time it changed.
