Solution: 

IAMSuiteAgent cannot be communicated through simple mode. No Never change IAMSuiteAgent from Open mode. 

If IAMSuiteAgent is changed to any other mode then above error is going to occur. In that case change OAM server instance mode and then change IAMSuiteAgent mode to open and restart servers . 

Oracle Documentation: 

Oracle Access Manager Console, IAMSuiteAgent Registration

The IAMSuiteAgent registration page provides details about the agent, like all other OAM agent registration pages.

• Security Mode: Open is the only security mode available for the IAMSuiteAgent. This cannot be changed.
• Preferred Host: IAMSuiteAgent is the pre-configured host required by this agent

Note:

The Access Client Password here must match the Agent Password in the WebLogic Administration Console. If you changed the Agent Password, you must also change the Access Client Password.

Figure 9-2 shows the IAMSuiteAgent page. Notice the User Defined Parameter, which informs behavior to fall back to the container policy in the WebLogic Server and provides a redirect URL for logout.
