404 - Invalid Host

The host "sphinx-doc.org" is unknown to Read the Docs

If you control this domain and believe this is in error, please review our custom domain documentation. In the past, we allowed custom domains to point to us without configuring the domain in the Read the Docs dashboard and we attempted to intelligently guess the correct project based on DNS settings. Now, we believe that explicit is better than implicit. Below are some steps to help you get your domain working again:

• Ensure you have a CNAME record pointing to readthedocs.io
• Add your desired domain in the Read the Docs dashboard for your project (under Your Project >> Admin >> Domains)
