Receiving "error=404: Project not found" on search for new builds

This is the message received when checking for new builds. I’m given reason to believe this was set up and working some time ago, using inherited credentials for the _ACCOUNT, _TOKEN, etc, but not sure if it’s been tested recently. Wondering how to debug such a problem. Is there a way I can test my environment settings, etc…any advice?

Solved. Unbeknownst to us, it was simply that the API token had expired. The error is very misleading.
