This error means that your sitemap couldn’t be processed by Google because it couldn’t be uncompressed. This is common for compressed sitemaps that are submitted in an archive file like .zip.

The Solution:

2. Empty Sitemap

You are likely to encounter this error if the sitemap submitted is empty. Improper tagging of URLs in the sitemap might also lead to this error because the Google bots cannot detect the information in the format.

3. HTTP Error (Specific Code)

This simply means that the sitemap couldn’t be processed or the bots came across some HTTP error that is not really critical especially when trying to have the sitemap downloaded. Note that some errors like 404 are critical but others might just show temporary errors like server problems.

The Solution:

Confirm is indeed the specified sitemap URL is accurate and is available at the location indicated. Once you are sure, simply resubmit the sitemap to Google Webmaster Tools.

4. Incorrect Namespace.

A namespace is an assortment of names that can be used as elements and attributes in an XML file. When you specify the namespace in an XML file, you are simply telling Google what kind of data contained in the sitemap plus their respective tags.

The Solution:

Give the sitemap a second look and ensure that the namespace is specified correctly. Once convinced that all is well, resubmit the sitemap.
