Does Instagram include blocking CDN URL requests from certain IP addresses?

Question

I recently noticed that for some cdn instagram url, the GET request gives an answer> 400.

https://scontent.cdninstagram.com/t51.2885-15/26184672_169643143794471_5913317750591193088_n.jpg

If I try to use the same URL from the same code from local, it works. so does it block content delivery by request IP address?

Answer 1

Since error 400 can be interpreted as:

• Invalid URL

• Invalid request

• Invalid request host name.

• The request could not be understood by the server due to incorrect syntax.

You may try:

• cookies
• DNS
