i have a site to which i added the required `<meta>` OpenGraph tags to, but is not displaying any Onebox previews. it is passing OpenGraph validation, so i doubt it is a markup issue.

(i cannot post a link to the validator, because i am a new user)

i can observe on the server end that it is indeed serving pages to the Discourse robot:

```plaintext
User-Agent: 'Discourse Forum Onebox v3.3.0.beta1-dev'
IP Address: 2602:fd3f:3:204:0:242:ac11:2d

```

but the links just do not show up:

> **[Authenticate with GitHub](https://swiftinit.org/docs/swift/swift/arrayslice)**
>
> No overview available

i considered that the problem could be because we return 505 HTTP Version Not Supported for `HEAD` requests, based on [this thread](https://meta.discourse.org/t/new-blog-wont-onebox/184448/10). so i patched our server to return a perfunctory 200 OK response for the `HEAD` method:

```plaintext
> HEAD / HTTP/1.1
> Host: swiftinit.org
> User-Agent: curl/7.81.0
> Accept: */*
> 

< HTTP/1.1 200 OK
< host: swiftinit.org
< access-control-allow-origin: *
< content-length: 0
< content-type: text/html; charset=utf-8
< 

```

however, this is still not working.
