You need to make your video publicly available...

Either set it to unlisted or public. Unlisted means you can post a URL to a video and anyone can follow the URL to see it but it is not listed in your youtube channel and doesn't show up in search results.

Public means it will also be listed in your youtube channel and in youtube search results...
Silly me - it was Public but I hadn't pushed the Publish button!
