We were hung up with [this bug](https://support.gluu.org/installation/5538/update-rcd-error-initscript-does-not-exist-etcinitdgluu-server-313-ubunutu-16044-lts/) preventing upgrading from 3.1.1 to 3.1.3 to see if would fix this bug.
Finally, figured out workaround to the upgrade bug so could see if fixed here.
Yes, now it is working.
