"Too many inaccessible URLs from the same domain" - what is this?
If some of the images were optimized and at one point ShortPixel stopped optimizing and then the error "Too many inaccessible URLs from the same domain" appears, then it could be because:
- Your hosting resources were exceeded. Check for out this article for a solution.
- You have a firewall or a CDN setting that prevents multiple connections to your website for the same IP address. Please check again if you whitelisted our IP addresses. We'd suggest to check this with your hosting too.
There are situations when whitelisting the IPs is not enough, because some hosting services block the ports we need in order to access your images. We recommend you to contact your host and ask them to allow api.shortpixel.com access on HTTP (port 80) or HTTPS (port 443).
If none of the images were optimized then here's a list of possible reasons and solutions.
