I just bought 2 domain from domaindiscount24.com. I get an error: "General HTTP error: 404 not found" when submitting sitemap. Then, I use "fetch as googlebot" and my website URL, it showed "not found". However, I make sure my website and sitemap work because I can access my website. Also, I use some online tools to check sitemap and they showed "valid sitemap". I don't know what happen. Maybe googbot don't want to access to these website. I am sure I am not block anything in htaccess and robots.txt
With domain I buy from godaddy, it is fine. So, what do you know what problem I facing ?
