Random 9002 Errors from iATS when making donations
Intermittent issues can be difficult to diagnose. A couple of notes that may help:

What you really need to do is to get TLS 1.2 and switch back to the www server. The www2 server is only needed for those not at the TLS 1.2 standard yet and is going to go away. Your lack of TLS 1.2 is probably a symptom of a system that is not up to date or maintained, that could well be the key issue.

Avoid any special characters in your iATS 80 account password; If you're using another than 80 account w/ iATS then confirm with customer services that you can deposit monies into that account via WebServices. If you're using more than one iATS subaccount 80, 81, 82 etc confirm all are able to accept monies via WebServices.
