Upon creating a new section.io application, the platform attempts to resolve your domain name to an IP address to use for your origin.
If your domain is using CloudFlare DNS at the time you create your section.io application, a CloudFlare IP address may be resolved and entered into your initial section.io configuration.
If you then attempt to use your section.io application via CloudFlare, a circular reference will be detected and a CloudFlare Error 1000 will be reported.
To correct this, browse to the Repository page in section.io Aperture and Edit the `section.config.json` file in the root of the repository. Change the origin address to the correct, non-CloudFlare, IP address or domain name for your origin server.
You can read more about changing your origin address in the section.io documentation.
