Hi @brmartinez
I hope you’re well today!
Some services do not really allow such link checking. A check is in fact an attempt to fetch the URL (it’s HTTP response headers, to be specific) and if they detect that it’s an “automated” check – like a “bot” or “crawler” that’s not authorized on their end – they just reject/bounce such requests.
This is particularly true with some main social platforms (as those on your screenshot) and also some services behind e.g. CloudFlare.
There’s no really way around that other that:
– for now, marking such links as valide, to ignore them
– over time adding various APIs support to our plugin
As for that “APIs” support part: we are working on some improvements for future, some APIs are already there (e.g. for YouTube) and we plan to add some additional gradually but this might take some time and still it may not be possible to provide support for all possible services that way, I’m afraid.
The “closest ones” would be support for Amazon MarketPlace links and to override CloudFlare “broken links” but I don’t have an ETA on this. I can confirm that our developers are working on it, though.
Kind regards,
Adam
