Grade Sync to Infinite Campus error "user not authorized"

[JodyGavers]

The past few years grade sync has worked flawlessly with Infinite Campus.  This year, we have not gotten it to work at all.  Infinite Campus says that the problem is not on their end.  We have contacted canvas multiple times with no response.  We use OneRoster and we are at a loss.  Has anyone ever had this problem?

Hello @JodyGavers , 

Thank you for reaching out to the Instructure Community regarding your question concerning syncing Canvas grades to Infinite Campus. Thank you for providing additional information as well concerning OneRoster. It is possible that we may need to update your school's authentication/integration information for Infinite Campus. Further, because of the complexity of the issue, and the concerns for privacy, it would be best if you contacted Canvas Support directly to pinpoint the source of the issue and provide a resolution:  How do I contact Canvas Support? - Instructure Community  . 

I hope this helps ! Again, thank you for reaching out to the Instructure Community.
