Here is what Oracle Support has to say about it.
For some upgrade scenarios, the Oracle Fusion Middleware Upgrade Assistant provides a Verify feature that attempts to analyze the upgraded 11g environment. When you run the Verify feature, the Upgrade Assistant automatically reports any problems it finds with the upgraded environment.
However, there are cases where the Verify feature incorrectly identifies a problem. For example, when single sign-on is enabled, the Verify feature might report that it cannot access specific URLs for the upgraded components.
In these cases, you should enter the URL directly into a Web browser to verify the URL. In those cases, the URL might indeed be valid and you can ignore the errors generated by the Verify feature.
