So I have a webpage that autogenerate og:tags for link preview on facebook, whatsapp etc. but whatsapp apparently can't scrape them. It works good on facebook but not on whatsapp. In whatsapp it just gives me this error message (see pictures. only somtimes, the other times nothing shows up) like the site has an error (which it doesnt have, you can access the page like any other page).
The og:tags are also correct in the tag in the site's source code.
Does anyone know why it is like this?
Did you post these links in WhatsApp already at a time, when they did not have og-data? Then you can try to delete all that links in the WhatsApp-Group-Media/Link-List and repost. That works for me with a similar issue with og-data in WhatsApp.
