An error occured: Empty JSON document (410 Gone HTTP Response)

I used the plugin successfully yesterday, however today on the exact same WP site I keep getting the following error message:

An error occured: Empty JSON document at https://realfavicongenerator.net/files/{REDACTED}/json_result.json

I can download the json file by going to the link, but doing a wp_remote_get() on the URL gives the following response:
