If you change the base URL of Identity Server, all Access Manager devices that have an Embedded Service Provider (ESP) need to be updated so that new metadata is imported. To force a re-import of the metadata, configure the device so it does not have a trusted relationship with Identity Server, update the device, reconfigure the device for a trusted relationship, then update the device. The following steps explain how to force Access Gateway to re-import the metadata of Identity Server.
On the Home page, click Access Gateways > Edit > Reverse Proxies/Authentication.
Select None for the Identity Server Cluster option.
Click OK > OK, and update Access Gateway.
Click Edit > Reverse Proxies/Authentication.
Select an Identity Server configuration for the Identity Server Cluster option.
Click OK > OK, and update Access Gateway.
