<p>I face a similar issue when I rapidly delete and then install my application using helm. You probably run into the following rate limit:</p>

<blockquote>
  <p>We also have a Duplicate Certificate limit of 5 certificates per week.
  A certificate is considered a duplicate of an earlier certificate if
  they contain the exact same set of hostnames, ignoring capitalization
  and ordering of hostnames. For instance, if you requested a
  certificate for the names [www.example.com, example.com], you could
  request four more certificates for [www.example.com, example.com]
  during the week. If you changed the set of names by adding
  [blog.example.com], you would be able to request additional
  certificates.</p>
