Getting DNS error for Twitter Card URLs

[SalarAdili]

Hi there. I have seen some other entries in the community about this but no resolution suggested. But I am receiving a DNS timeout for a bunch of URLs that I am trying to setup Twitter cards for. They’re mainly NIH institution URLs. How can I request the Twitter Card DNS server to get updated with these URLs? They’re available on public DNS.

error message: ERROR: Failed to fetch page due to: DnsResolutionRequestTimeout

e.g. https://www.nichd.nih.gov

Thanks,
Salar

It’s very likely that our internal DNS cache used by the cards crawler is not seeing those domains for some reason. I’m not sure what the cause might be.
