URLs roboted out
When we tested a sample of the URLs from your Sitemap, we found that the site's robots.txt file was blocking access to some of the URLs. If you don't intend to block some of the URLs contained in the Sitemap, please use our robots.txt analysis tool to verify that the URLs you submitted in your Sitemap are accessible by Googlebot. All accessible URLs will still be submitted.
