There are three different SSOs (Single-Sign-On) "links" that have been used to enable sign-in to CXone. The most current one which most users are now using is SSO3. We would recommend trying SSO3 unless you are certain you are still using the older SSO links.
The links are:
SSO3 - https://cxone-gov.niceincontact.com/auth/authorize?response_type=code&scope=openid&client_id=0b697ebb-4ea2-4052-b12b-d3cf12a53eca&redirect_uri=https%3A%2F%2Fcxone-gov.niceincontact.com%2Fua%2Fv1%2Fcallback&tenantId=11eac2e5-be7a-8020-91cc-0242ac110002
SSO2 - https://account.activedirectory.windowsazure.com/applications/signin/583dbaa3-c704-4deb-a71d-3dee8830a053?tenantId=9a307864-3e98-4f08-b90a-728b62cf32c5
SSO1 - https://account.activedirectory.windowsazure.com/applications/signin/089affb1-9d75-4168-8361-0bac4f4615da?tenantId=9a307864-3e98-4f08-b90a-728b62cf32c5
