Hi there, I'm using Marketing API, to push ad campaigns, everything worked just fine, until recently I started getting such error that blocks me from posting campaigns:

3858258: Image Wasn't Downloaded | Your image, https://storage.googleapis.com/this-image-is-available-and-public-on-internet.jpg, couldn't be downloaded. Please ensure the image is accessible via the internet and is not blocked by a robots.txt

Does that rings a bell for anyone?
