Issue/Introduction

This article addresses startup connectivity failures between Identity Portal and Identity Manager (IDM) when the connector logs report an HttpRequestMethodNotSupportedException: Request method 'GET' not supported.

Environment

Identity Portal 14.5

Identity Manager 14.5

Cause

The HttpRequestMethodNotSupportedException during Identity Portal startup typically indicates a configuration mismatch between the Identity Portal connector and the Identity Manager environment. This often occurs when the connector attempts to invoke a method (GET/POST) not supported by the current endpoint configuration.

Resolution

To investigate and resolve this connection error, perform the following troubleshooting steps:

1. Verify Connector Configuration: Navigate to the Identity Portal Admin UI and verify that the IDM connector configuration parameters (Host, Port, and Protocol) are correct.

2. Inspect Connector Logs: Review the Identity Portal connector logs to identify the specific URL being accessed when the HttpRequestMethodNotSupportedException occurs. This often points to a misconfigured endpoint.

3. Validate Endpoint Compatibility: Ensure that the version of the Identity Portal connector installed is fully compatible with the Identity Manager release.

4. Restart Connector Service: After making any configuration changes, stop and restart the connector service from the Identity Portal Admin UI to apply the changes.
