Why am I getting an IP Address Not Allowed error message using SOAP?
Oracle Service Cloud version May 2013 and newer, Connect Web Services for SOAP API
There are many reasons to get the Access Denied message but because of increased security on Oracle Service Cloud version May 2013 and newer, there is a new configuration setting that needs to be set if you are connecting through SOAP API and not having this configuration set will cause the above error.
Check your SEC_PAPI_INTEG_HOSTS_SOAP setting and add your IP Address, domain names with wildcards or subnet masks (for example, *.rightnow.com,220.127.116.11, 10.11.12.0/255.255.255.0) if applicable.
Default is blank.
