Checklist for Troubleshooting Node Manager SSL Problems

1. Check what certificates are being used. Demo, Commercial, self-signed?
2. In the case of demo certificates make sure none of the settings are changed. You don't need any entries in the nodemanager.propertiesfile. Nor you do not need to make any changes to the settings in the admin or managed server.
3. In the case of commercial certificates (Verisign, Thawte, Comodo, etc.) make sure that the certificate chain is complete and the root and intermediate certificates are configured properly.
4. If the certificates are self-signed, make sure you have followed the sequence mentioned earlier in this document.
5. Make sure that the validation dates are correct.
6. Turn on the debug flags on both admin server and managed server to get all possible information.
7. Node manager debug flag. This flag needs to be added to the start script
8. (The log files are located under <NodeManagerHome>/nodemanager.log)

• -Dssl.debug=true -Dweblogic.StdoutDebugEnabled=true

• -Dweblogic.StdoutDebugEnabled=true -Dweblogic.nodemanager.debugEnabled=true -Dweblogic.nodemanager.debugLevel=90
