Do you observe any error messages in the /var/log/apm file on the BIG-IP APM and client side log files ($HOME/.F5Networks/*) per K00984153: Troubleshooting issues with the BIG-IP APM Linux f5fpc client? Can you also try replacing the ipv6 address with a host name (adding an appropriate entry in the /etc/hosts file)?
