Today I'm here with a fresh issue that I never seen before. I have converted my site from asp to aspx(.net) on this weekend. After finalizing the website I went through sitemap submission on google. I previously ran xml sitemap on google and that works fine for me. But now when I again went for it, doesn't work for me. A message appears while submitting a sitemap extension of xml in google "googlebot is restircted by the robots.txt file. I don't know where I did mistake. I have checked again and again robots.txt file but got nothing. The issue is still there, and I'm feeling that my ranking going down for that instance. Please help me out what to do, where to look and what must be there if googlebot is restricted by somewhere on the site.
