Link Web Part Not Generating Preview
Here is the code for a trivial Web Page I am hosting in IIS on a Non-SharePoint machine:

This is a test page.

When I the type the URL for that Web Page into a Link WebPart on SharePoint Online, I get this "error":
"There's no preview available for this link."
What do I need to change in the above code, to get the Link Web Part of SharePoint Online to display a preview?
It seems like a bug - especially considering that the Use the Link web part page shows a preview image to an external site.
I'll report it to MS Support and report back.

BTW: I know this is off topic, but it would be nice if this forum:
- Allowed me to edit my posts
- Would pretty format my code
I'm still having problems with this. As an example, if I post this URL in MS Teams:
https://www.microsoft.com/en-us/microsoft-365/blog/I get a URL Preview:
but when I try to put the same URL in the Link WebPart of a SharePoint Online page, I get a "There's no preview available for this link." message:Shawn Eary Having the same issue, but it shows the preview on some SharePoint sites and not on others for the same exact link.
