Your wiki uses the new platform. This is a known issue with the new platform but Fandom has not made any public commitment as to when it will be fixed.

For security reasons, Fandom does not allow the posting of mini URLs. When you import a YouTube video, it attempts to copy the YouTube video description as the video's initial page content. The video you are trying to import contains several mini URLs in the video description. Therefore, when the import tool attempts to copy the YouTube video description as the initial page content, it trips the global abuse filter. The global abuse filter then prevents the import.
