Last few days I tried to implement Twitter Cards for blog post sharing. However one of my clients’ site is not validated by Card validator with below error message. I check everything I can with developers document but I have no idea how to fix this.

ERROR: Fetching the page failed because the fetcher cannot resolve the address.

Looks like a network error in trying to resolve the site’s DNS address. Not sure why that would be the case. You might want to confirm that there’s no issue with access from Twitter’s IP range - there’s information on these and the ASN on the troubleshooting page.

Thanks @andypiper. Do I need to check DNS server or web application server?

I’d recommend checking both.
