Can't display OGP image

[ryuapp]

Hello.
Fresh site can't display OGP image.
https://fresh.deno.dev/
But for some reason the docs displays the image.
https://fresh.deno.dev/docs/introduction

Is this bug in Fresh or Deno Deploy?

What's an OGP image?

[ryuapp]

Sorry, I don't know the appropriate words in English.
"OGP image" I said means og:image in meta tag.
It refers to the thumbnail image that is displayed when a URL is detected on SNS.
ex. <meta property="og:image" content="https://example.com/og/image.png">

On Fresh site, both have the same tag, but only the docs has the image displayed.
Check following this screenshot or paste https://fresh.deno.dev/ in Discord.

The OG image in https://fresh.deno.dev/ is not displayed because it will redirect all other than the specific user agent when it doesn't have any header.
