Why did I get result codes 102, 103, 104 and 106 (Sandbox)?

While you were working in the Sandbox environment, PayPal presented result codes 102, 103, 104 and 106.

Result codes 102 (Processor not available), 103 (Error reading response from host), 104 (Timeout waiting for processor response), or 106 (Host not available) may occur in the Sandbox environment for the following reasons:
  • Your Sandbox account may not be set up correctly, or you're trying to use a credit card that can't be used in the Sandbox environment.
  • Your account currently can't communicate with your processor.

If you're testing in Sandbox using Payflow Pro, use card numbers from a "Personal" Sandbox account rather than the test card numbers listed in the Payflow Pro Developers Guide.
