Photo download scripts are receiving a forbidden error


We are receiving a Error 403 Forbidden when we attempt to pull the images from the photo url. I can place the url in a browser window and it displays but I can not pull it from my rets script. This just started today from what I can see. 2022-08-02 12:38:57 ERROR 403: Forbidden.

This is our IP -

Please advise! This is happening on Multiple MLS systems for Paragon only.

Thank you in advance!

Best regards, Sean

When pulling images by URL from the CDN. There is a Rate limit of: 5000 requests within 5 minutes, per IP Address, across all "cdnpara*" image URLs. When the limit is exceeded, the IP address is then blocked for several hours and a 403 error is returned while it is blocked. Limits were implemented to address abuse and to ensure stability of systems for our customers. To avoid this, you can add delays between image requests and/or you can also use multiple IP addresses, especially if you access multiple MLSs

Can we get this unblocked. It has been blocked since 7:00 PM ET last night?

Just curious, do you recommend we download copies of images rather than link to them directly on our products? Right now they're linked to, but are proxied through our server, so all requests would come from the same IP but it's directly serving customer traffic, so there would be no practical way for us to self-rate limit with this approach. But, downloading copies would undoubtedly generate more traffic on your end because it would mean resolving EVERY photo, regardless of whether anyone wants to see it.

From what I understand, you should be unblocked now.
Not sure what the best answer or way to do this would be.
You could just pass the URL through directly which should be ok as long a traffic isn't super heavy.
Or since you are proxying, maybe you could do both.
When a link is clicked, download the image to a local image cache, then the next time the same link is clicked, return the cached version?
