Alex Vojacek · October 21, 2014

Hello guys

I did hundreads of test on the IPN issue, I filled IPN field in Paypal with:

mydomain/callback/gw/paypal_payments_standard

And yet when I do a IPN test on

https://developer.paypal.com/webapps/developer/applications/ipn_simulator

the return is this in the logs:

/callback/gw/paypal_payments_standard

Error.

And my payments are done but they are not checked on blesta.

I double checked nginx configuration i'm using the recomended blesta 3.0 config that was posted earlier on this forums and on the web.

I'm using a standard VPS with Centos 6.5 and remi nginx pack with php 5.4

Everything else seems to be working just fine.

Any ideas on what may be wrong?

Maybe it is related to this ?

What do you guys think?

Michael · October 21, 2014

Are you using the primary email address?

Alex Vojacek · October 21, 2014

Yes i am using the primary e-mail address.

Paul · October 21, 2014

PayPal now requires HTTP 1.1, if your server is sending HTTP 1.0 headers then they will reject it. Blesta doesn't set this header, so it is likely set by CURL. Are you running an old version?

Alex Vojacek · October 21, 2014

I'm running latest nginx with remi repositories on CentoOS 6.5 with php-fpm.

This is all latest packages and i double checked with the nginx log and all connections are done through http 1.1

Blesta Addons · October 21, 2014

have you any custom rule for mod security ?

Alex Vojacek · October 22, 2014

No, because i've stated i'm not using Apache, i'm using nginx with no extra security or any module outside what blesta recommends.

Alex Vojacek · February 11, 2015

Ok, this is driving me nutz.

I redid the whole VPS and used Apache instead, tried apache 2.2 and apache 2.4 same thing, same error, my friend moved blesta to our interworx installation and now it's working, i want to find out WHY it's not working on my webserver, i did EVERYTHING by the rules.

Can anyone profficient enough with blesta point me in the right direction?

This guy found out that if paypal does not recive a header with at lease a User-Agent: something it wont work, i forced the header on nginx and apache to no avail...

I've never tried the PayPal when I used no control panel to install Blesta but everything worked on:

Centos 7

PHP 5.4

MariaDB

Apache 2.4

So..

maybe in your paypal account, fill the return url.

by the way only ipn url automaticaly given by api call will be used in place of what you filled above, but maybe you need to fill it at paypal for like enable it on their side.

I'm did that way & selling from 2 websites, it's alway ipn url from api call that is used, so it's return or notify or customer back to the good website
