Ummy unable to resolve link info

Using version 1.10.7.2.  Some links will not resolve, such as

After Ummy connects and gets info, the correct image for the video comes up, but no link is established and the message "Insert a link to a video or playlist" comes up.  Reloading the link always produces the same result.
