Hello everyone,
I don’t understand why I don’t see the preview of the amazon links.
Here it works perfectly but in my forum that I updated today ( 9581d71372 ) it doesn’t.
Can it be cloudflare’s fault?
When you’re writing a post, do you see an error like this in the preview?
There are some Amazon issues we’ve been running into where previews (oneboxes) have been hitting what seems to be a rate limit… we’ve made improvements in the past couple of weeks to try to avoid this, but it’s not completely solved and we’re looking for better options.

Thanks for your help Kris.
No, only a white box with Amazon
I also cleared the cloudflare cache.
PS. Here on meta works perfectly.
Sorry I forgot, this is the list of installed plugins.
I also tried on others Discorse forums and the preview doesn’t work, it only works here on meta 
Nothing I give up … I have tried everything but I don’t understand what blocks the preview of the Amazon links.
OK I found other useful information, I am writing because it could be useful to someone…
The problem is the same:
If I run curl https://www.amazon.it/dp/B07YSF42TT -v -o deleteme I get error 503 so I give up.
Do you know if there is another way to add an image and a short description?

We get the same thing on our Discourse (v2.7.0.beta7( 42f6c9b6b9 )) when trying to share Amazon links:
And in the composer view:
I just put it down to never-ending Amazon issues.
Unfortunately no, I think your VPS is also blacklisted 
Sorry, yes, that’s what I meant

Using curl -A "Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:59.0) Gecko/20100101 Firefox/59.0" https://www.amazon.it/dp/B07YSF42TT works fine, but now… how to change onebox useragent?
Also curl https://www.amazon.it/dp/B07YSF42TT -v -o deleteme -H "User-Agent: Discourse Forum Onebox v2.7.0.beta7" works.

I don’t understand where I’m wrong…
OK, it only works with amazon.com
.es, fr, de, it and others don’t work, it’s definitely a bug!
Hi all, I have updated to version 9ebc9541b9 and now the preview works on all amazon sites!
Thanks

I recommend a posts:rebake to generate the preview even the old messages.
./launcher enter app
rake posts:rebake

I would not recommend a rebake at all.
Amazon very will likely block your server IP address for hammering on their door.
