Thread: This transaction cannot be accepted.

Hi, we have Authorize.net as payment Gateway.
it was working fine, suddenly from two days we noticed all credit Card transactions are being declined

a error message as This transaction cannot be accepted.
when customer choose Credit Card payment method.

what could be wrong.

Just for your information API login and trans key are working fine, we use the same API login and transkey for other website, it working perfect there.

please help with this issue.

thanks

What does your failed transaction log say?

Also double check no server configuration has changed - we had an issue with this gateway and one hosting provider who'd changed their trust levels to Medium and as a result outbound connections were being silently rejected.

If none of this helps, it's possible to build a modified version of the Authorize.net gateway with additional debugging information to try and help diagnose the issue but you'll need the source code.
