The error "... BEA-090482 ... BAD_CERTIFICATE ... hostname verifcation ..." indicates that the common name (cn) of the server's private key does not match the expected server name.
This is very good documented under
Limitation on CertGen Usage.
To solve the issue correct the common name (cn) of the private key or disable host name verification (
Java option -Dweblogic.security.SSL.ignoreHostnameVerification=true).
If you are using the WebLogic demo identity and trust you can create a new private key with these commands:
JAVA_HOME=/opt/weblogic/jdk160_14
WL_HOME=/opt/weblogic/wlserver_10.3
PATH=$JAVA_HOME/bin:$PATH
export PATH
. $WL_HOME/server/bin/setWLSEnv.sh
java utils.CertGen -cn YOURSERVER.DOMAIN.COM -keyfilepass DemoIdentityPassPhrase -certfile mycert -keyfile mykey
java utils.ImportPrivateKey -keystore DemoIdentity.jks -storepass DemoIdentityKeyStorePassPhrase -keyfile mykey.pem -keyfilepass DemoIdentityPassPhrase -certfile mycert.pem -alias demoidentity
Copy the newly created demo identity key store to $WL_HOME/server/lib directory.
