I trying to configure SSL for my weblogic server 12.2.1. I created self-signed keystore and truststore SSL certificates using JDK keytool utility, configured it through the Admin console, set "SSL listen port enabled" to true and changed it to 8888. After all, I deployed my web service to the server. So, web service works on https with no problem. But when I want to restart weblogic, I get this error:

javax.naming.CommunicationException: t3s://localhost:8888: [RJVM:000575]Destination 0:0:0:0:0:0:0:1, 8888 unreachable.; nested exception is: 
java.net.ConnectException: Connection refused: connect; [RJVM:000576]No available router to destination.; nested exception is:

java.net.ConnectException: Connection refused: connect; [RJVM:000576]No available router to destination.; nested exception is: 
java.rmi.ConnectException: [RJVM:000576]No available router to destination.]

Problem invoking WLST - Traceback (innermost last):
File "C:\Oracle\Middleware\Oracle_Home\user_projects\domains\base_domain\shutdown-AdminServer.py", line 3, in ?
File "<iostream>", line 19, in connect

WLSTException: Error occurred while performing connect : Cannot connect via t3s or https. If using demo certs, verify that the -Dweblogic.security.TrustKeyStore=DemoTrust system property is set. : t3s://localhost:8888: [RJVM:000575]Destination 0:0:0:0:0:0:0:1, 8888 unreachable.; nested exception is: 
java.net.ConnectException: Connection refused: connect; [RJVM:000576]No available router to destination.; nested exception is: 
java.rmi.ConnectException: [RJVM:000576]No available router to destination.

What is the reason for appearing this problem? How to fix it? I also checked config.xml and it contains actual information about port. For developing I use Eclipse Neon. Thanks.

  • @devwebcl I have already seen this post and I tried to use solutions that described there but it doesn't help...Are there any other ways to resolve it? – Nick Sheinov Nov 20 '18 at 00:34
  • Are you restarting the admin server or a manager server from the same domain ? – Emmanuel Collin Nov 20 '18 at 12:15
  • @EmmanuelCollin yes, I have only one domain and I restarting server using eclipse. Console prints error as above. – Nick Sheinov Nov 20 '18 at 17:37
  • As far as I can tell, wlst does not trust the self signed certificate of the AdminServer, when executing the shutdown-AdminServer.py. I think that you need to import the self signed certificate to the default java's trust store (cacerts) using java keytool. – komarios Dec 04 '18 at 12:57
  • @komarios, but this error also occurs when I trying to use demo certificate. – Nick Sheinov Dec 04 '18 at 14:11
  • If you are using Demo certs, the error clearly states that you need to use "-Dweblogic.security.TrustKeyStore=DemoTrust" as a JAVA_OPTIONS startup parameter. Otherwise, you would need to import the demo certiifcate inside cacerts as well. – komarios Dec 11 '18 at 07:29
  • @komarios, so, where can I set JAVA_OPTIONS startup parameter? – Nick Sheinov Dec 11 '18 at 15:18
