Googlebot Not Crawling my site ?

For the last two days, Google is not crawling my site, I’ve checked everything in Webmaster Tools, but still fetch as Googlebot showing failed status. I’ve also checked Robots.txt file, and it’s also looking fine.

I’ve also talked to my hosting company, and they have given me thumbs-up from their side. My site is also coming in the search results.

So, what might be the problem now, plz tell me ? I’m really getting tensed. This is my site https://wikitop5.com/
