Preview Fail: “Unable To Identify Your Browser”

Hi,

While trying to insert into a post a link (using Gutenberg) to an article found in Manta, the preview image and excerpt fail to load:

“Unable To Identify Your Browser
As you were browsing https://www.manta.com something prevented us from identifying your browser. There are a few reasons this might happen:”

Here’s the link to the article in question:

Any solutions to this would be appreciated, Thanks!
