Connection refused; No available router to destination On Weblogic Node Manager Log

Posted on by Osama Mustafa in Fusion Middleware

Caused by: java.net.ConnectException: t3://exalytic.domain:8001: Destination unreachable; nested exception is:

The Above Error Appear when i was trying to access BPM, the main Cause for this error there’s no configuration protocol on SOA Server Which mean No Listening Host.

To Avoid and Solve this error Follow the below Steps :

  • Access to weblogic Console using Administrator Password.
  • Click on Servers -> Protocols -> Channels like the below screen
  • Now you have to create new Protocol Click on “Configure a new Network Channel,”with the below confguration 

Name: Loopback
Protocol: t3
Listen Address: localhost
Listen Port: 8001 (same as Server Host/port)

  • Restart The Server and test the connection Again 

Thank you
