Problème avec les Bookmark / oEmbed

Hello .
I’m asking you to address an awkward problem with the bookmark feature.

Since a few weeks (ghost 3.17.0), some sites not work with the Bookmark feature.
The oEmbed works for many sites, but no longer for ours.

When adding the link in the editor, we get an error 422
GET /ghost/api/v3/admin/oembed/?url=https%3A%2F%2xxxxxxxxxxxxxx&type=bookmark HTTP/1.0

Same error without bookmark GET /ghost/api/v3/admin/oembed/?url=https%3A%2F%2Fxxxxxxxxxxx%2F HTTP/1.0

I’ve done a lot of research to correct the problem, I think I’m forgetting something.

Ghost 3.25.0 (bug since 3.17.0 update)
Ubuntu or Debian with Plesk Obsidian
Node 12.4.0

Thank you in advance for your help.

Damien
