Common mistakes: HTTP Practical Demonstration DCV method

To demonstrate control over your domain using the HTTP Practical Demonstration DCV method, DigiCert provides you with a URL and a token value. The URL does two things:

  1. It contains the FQDN (fully qualified domain name) of the domain you want us to validate.
  2. It tells us where to look so that we can find the verificationtoken.txt you add the generated random value to.

In this section are some of the more common issues we run into when troubleshooting the reason HTTP Practical Demonstration checks fail. The HTTP Practical Demonstration DCV process was designed to keep an unauthorized individual from using a domain they do control to validate and get a certificate for a domain they don’t control, such as one of yours.
