Several days ago we mentioned the AdSense Adv did not show up on our website but just display error message:
This web page is not available.
It still come often. We checked the Google and found lots of people get same issue but seems no any perfect solutions, some reason might be robots.txt, or might because something blocking chromes access to the internet such as a firewall or anti virus program….etc.
Although we have not a final solution, but we provides one way which worked for us: the thing is simple, plug out the power cable from your network modem, turn off your router, … etc. After about 20 seconds and re-start them.
After your high speed networking come again, you might see you have already resolved your problem, the AdSense adv come again.
