URL is Inaccesible

[HiteshP]

Hi,

I have tried this url: https://www.3dquickprinting.com/ on Moz onpage grader but it responds "Sorry, but that URL is inaccessible." I have checked my Robots.txt but it does not have any entry to block MOZ crawler. Please see:

#User-Agent: *
#Crawl-Delay: 30

#For robots.txt
User-agent: BLEXBot
Disallow: /
User-agent: MJ12bot
Disallow: /
User-agent: TwengaBot
Disallow: /
User-agent: 008
Disallow: /
User-agent: WotBox
Disallow: /

Please advice what to do get rid from this error.

Thanks,

Hey, Dave here from the help team!

On Page Grader is uses DNS checks to validate and it looks like all of your nameservers are not valid.  You may want to start looking there.  I also responded to your help ticket, if you have any follow-up questions, feel free to hit me back there!
