Hi,
Can you check the port number and the listen address which you are using to access the console/app from the browser?
Are you using HTTP port or HTTPS ?
If HTTP, then can you check whether the HTTP port is actually enabled or not in Weblogic ?
The best part to confirm this is to check the out file of the server and see on which port/ listen address the server is listening too and use this information
you should be able to access the console and you application.
Regards,
Robin
