In the Admin console Some Managed Servers Do not Show a Health Status due to SSL error (Doc ID 2437501.1)

Last updated on AUGUST 20, 2018

Applies to:

Oracle WebLogic Server - Version 10.3 and later
Information in this document applies to any platform.

Symptoms

When going to the admin console to check the health status of the managed servers configured, it shows that some of the servers have "OK" in the Health column but some of the them just have the column blank.

The servers with blank health status have the following error in the log:

Changes

 This happens after the admin server is configured to use custom identity keystore and trust keystore and non-ssl port is disabled.
