SOLUTION 

1. Launch a browser window.
2. Go to Connection Settings for the Browser
3. Select the Proxy exception list, the list of sites you have specified, for which no proxy is required
4. Verify / validate all entries in this list.
5. For Example, you will need to add an entry like *.oracle.com instead of oracle.com to exclude all sites having oracle.com in the domain name.
6. Save the changes.
7. Login and access the Applications forms in a new browser window.
