Why did I get result code -12?
PayPal returned result code -12 - Timeout waiting for response.
Cause
During transaction processing, the connection between your server and payment servers failed.
Solution
Here's how to resolve this issue:
- Check PayPal Manager to determine whether the transaction has posted. If it hasn't, try again.
- If you're using the Payflow SDK, try the following:
- Increase the timeout parameter value to 90.
- Investigate the issue internally with packet sniffer software.
- Remove memory- or resource-intensive applications running on the same box, or create a dedicated server for the Payflow Pro SDK.
If you're using a UNIX environment or have an open source tool (such as Cygwin), you can try the following commands to check connectivity:
- Run command line using cURL:
curl -d -v https://pilot-payflowpro.paypal.com - Run command line (OpenSSL):
openssl s_client -connect payflowlink.paypal.com:443
If the condition continues, submit a question to PayPal.
