CM-REQ-4159 | CAM-4005 | CAF-WRN-2082 while scheduling

[CognosUser101]

We're trying to schedule reports with a service account. These scheduling configurations had been setup, but were not enabled for some time. I can run the reports manually.

When I try to run the pre-configured reports through a schedule, I get the error:
CM-REQ-4159 Content Manager returned an error in the response header. The error "cmAuthenticateFailed CM-CAM-4005 Unable to authenticate. Check your security directory server connection and confirm the credentials entered at login." can be found in the response SOAP header. CAF-WRN-2082 An error has occurred. Please contact your administrator.

I tried renewing credentials and it still throws. I also tried taking ownership of a report and remaking the schedule entirely, and the schedule doesn't even trigger, resulting in no errors at all.
