validateIpnContent: Error while posting IPN: , 0

[artaxx]

Hi there,

I know that a lot of people do have this problem but after trying all solutions provided bei this forum and Google I have to ask here. Sorry for that!

Joomla: Joomla! 3.6.5 Stable
PHP: 5.5.38
Virtuemart: VirtueMart 3.0.18

I configures the IPN on Paypal with Return and IPN but I always get this error after paying.

What I've done:
- Checked Reverse Proxy => none
- Checked OpenSSL => activated
- Double-Checked the Return and IPN Settings in Paypal Profile
- Changed locale to UTF-8

Are there any other solutions for this problem?

Thank you!

I had a similar problem. But as I understand it, no one has given an answer? Maybe someone in the know, could this be due to misconfigured proxy server? Thanks in advance.

Do you use the paypal sandbox or production setting? See here: https://www.paypal-knowledge.com/infocenter/index?page=content&id=FAQ1914
VirtueMart PayPal Standard is using:
https://api-3t.sandbox.paypal.com
https://api-3t.paypal.com

If you check your website's domain with this tool: https://www.sha2sslchecker.com
does it find 'sha256WithRSAEncryption' or something else?

If you can't find a solution, you may consider to set IPN to 'Off' in you PayPal account settings. I've never enabled it and PayPal works fine. I do get 'you received a paypment' emails from PayPal without IPN enabled.
