PHP Curl return 404 from aws but works from other host and even my machine

Been banging my head over this for awhile. I have written php code to search the website https:paytm.com which works from the other hosting site I have been with earlier but not from AWS.

My machine is running ubuntu with php7, curl is installed and running. the search using curl works for other sites, curl https also works. the same code works brilliantly on the other host (via ssh as well as frontend), it even works from the browser.

The url I am trying to access is curl -v 'https://search.paytm.com/search/?page_count=1&items_per_page=10&quality=high&curated=1&cat_tree=1&from=organic&channel=web&version=2&userQuery=iphone'

Things I have checked:

  1. The certificates are up to date
  2. The code works fine on my machine and other hosting provider
  3. AWS setup is ubuntu 12.04, running php
  4. Setting up the machine again
  5. Running the script from browser
  6. Checking https curl on google, twitter, linkedIn from my aws setup, they work fine.

The resulting response coming from my AWS setup is:


    ubuntu@ip-172-31-20-200:/usr/local/share$ curl -v https://search.paytm.com/search/?page_count=1&items_per_page=10&quality=high&curated=1&cat_tree=1&from=organic&channel=web&version=2&userQuery=iphone

Really stumped as to what to do, tried searching stackoverflow to the core and found few solutions like setting cookies or user agent but both doesn't work, also if you see the user-agent string for the other hosting is also set to the same and yet it returns the correct response, heck it even runs the same version of ubuntu. Would be awesome if I could get any help regarding this from the community.

To wrap it up, my skill level in ubuntu, terminal, ssh, etc is just newfound so you might have to lay down the terms and help in basic way... sorry for that.

Turns out that the AWS entire range of IP is blacklisted which is the reason for the error to pop up.

search.paytm.com is being hosted on the Akamai CDN, so different clients are routed to different servers. Notice that your first connection went to 96.6.72.42 and the second one went to 23.218.97.132. When I look up the hostname I get different IPs, alternating between 104.97.19.53 and 23.203.115.39; I'm located in Boston using Comcast, and traceroute shows that those are located in Comcast datacenters in Boston and New York City.

For some reason, the page you want is only located on the second server. This is a problem with their configuration, you need to contact them.

Your problem is you're not escaping your url. The &'s mean something to the shell.

Try the following:

curl -v 'https://search.paytm.com/search/?page_count=1&items_per_page=10&quality=high&curated=1&cat_tree=1&from=organic&channel=web&version=2&userQuery=iphone'

The clue is this output:

[1] 26241
[2] 26242
[3] 26243
[4] 26244
[5] 26245
[6] 26246
[7] 26247
[8] 26248
[2]   Done                    items_per_page=10
[3]   Done                    quality=high
[4]   Done                    curated=1
[5]   Done                    cat_tree=1
[6]   Done                    from=organic
[7]-  Done                    channel=web

Those are shell background jobs. It is literally trying to run the following commands and put them into the background:

$ curl -v 'https://search.paytm.com/search/?page_count=1 &
$ items_per_page=10 &
$ quality=high &
[... and so on ...]

The fact that the 2 systems resolve to 2 completely different IP ranges on the same host name suggests that the target IP was recently changed, yet your system that fails is still getting the old IP as a DNS response.

Suggest using Google's free DNS servers.. https://developers.google.com/speed/public-dns/docs/using#linux
