Solution:

Open the startManagedWebLogic.sh file under /home/weblogic/Oracle/Middleware/user_projects/domains/base_domain/bin and find

JAVA_OPTIONS="-Dweblogic.security.SSL.trustedCAKeyStore="/home/weblogic/Oracle/Middleware/wlserver_10.3/server/lib/cacerts" ${JAVA_OPTIONS}"

change into

JAVA_OPTIONS="-Dweblogic.security.SSL.trustedCAKeyStore="/home/weblogic/Oracle/Middleware/wlserver_10.3/server/lib/cacerts" ${JAVA_OPTIONS} -Djava.net.preferIPv4Stack=true"
