Troubleshooting Tips: Developer Portal Destination

I see that when webMethods API Gateway and webMethods Developer Portal are deployed on different machines, configuring webMethods Developer Portal as the destination fails.

When webMethods API Gateway and webMethods Developer Portal are deployed on different machines, configuring webMethods Developer Portal as the destination fails with the following error message when I click the Test button, "The input url https://sawld01.cmcdev.be:18102/portal/rest/v1/providers?tenantId=default is not allowed as the host is in denied list. Contact administrator".

Resolution:

Using the REST API, update the webMethods Developer Portal's IP address in the webMethods API Gateway's whiteListedIPs /rest/apigateway/configurations/whiteListingIPs
