There has been a new feature addition called “site diagnostic” in Adsense. Here is more infomation for you:
—-(From Google)—-
What is the site diagnostic feature?
The Site Diagnostics page within your account provides details about whether our crawler was able to access your site in order to provide relevant ads. Our crawler sometimes encounters errors when attempting to crawl a page to determine its content. Using the site diagnostic section of your account, you can review the errors our crawler encountered for specific blocked URLs, then correct them in order for us to crawl and deliver the most relevant ads.
—-End—-
You can visit your Adsense account for more.

Hello Rajendra Ale Magar,
While going through our records recently, we found that your AdSense
account has posed a significant risk to our AdWords advertisers. Since
keeping your account in our publisher network may financially damage
our advertisers in the future, we’ve decided to disable your account.
Please understand that we consider this a necessary step to protect the
interests of both our advertisers and our other AdSense publishers. We
realize the inconvenience this may cause you, and we thank you in
advance for your understanding and cooperation.
If you have any questions about your account or the actions we’ve
taken, please do not reply to this email. You can find more information
