IPs to be whitelisted
If you get a 403 error or your images are not accessible from our servers, then please check if you, or your hosting provider, have a security plugin or a firewall which prevents our servers from accessing your images.
If this is the case, please whitelist our IPs:
The IPs are also available as a JSON here.
You may also need to whitelist the above mentioned IPs if you are using ShortPixel Adaptive Images or Autoptimize plugins and notice that the images, instead of being served from CDN, are served from their original location with a redirect.
