Smush server was unable to access images from your site.

Hello,

We haven't had much success using the WP Smush Pro product yet. Right now we are stuck at a message that says "Smush server was unable to access images from your site." Before this point, we have tried bulk smush requests. I receive a notice of completion, but the fetching does not seem to work. Also, when I check the WP Smush Pro screen in WP Admin, it looks like the images are still processing. Can you help? I have enabled support access.
