This error doesn’t have to do anything with CPQ, it is on C4C side.

Troubleshoot IDP (SAP IAS) issue

Note: In C4C integration with CPQ, the CPQ application is opened inside iFrame.

When the session expires on IDP, the next user’s action will send a request for authentication which IDP recognizes as a C4C request (because cpq is opened inside iFrame in C4C). Since the request looks like sent from C4C and not CPQ, IDP will deny it and mark the domain as untrusted.

For solving this, the C4C URL should be added as a trusted domain.

Admin -> Application & Resources -> Tenant settings -> Trusted Domains.

In the screen opened, you will have a field to add URL host application where you should add C4C URL.
