Verify the Status of Location-Based Access Control (LBAC)
Check if you have enabled Location-Based Access Control (LBAC) for Fusion Applications (for Oracle ERP Cloud).
If LBAC is enabled, you must allowlist (explicitly allow identified
entities access) the Oracle Integration NAT Gateway IP address in your LBAC. If you
do not perform this task, you can receive a 401 Access Denied
error
or 403 Forbidden
error from Oracle Fusion Applications.
