Sitemap Error from Google Search Console

Hi -

I am getting a sitemap error for my sitemap in the following ways:

  1. > does not resolve
  2. Google Search Console is throwing this error: Please enter a valid path to a sitemap in your site.
  3. is throwing this error: Incorrect http header content-type: “text/html” (expected: “application/xml”)

I have “auto generate” sitemap checked. Any ideas?
