Auditing in Vault 1.1.0 not working

We have a three node Vault 1.1.0 cluster on CentOS 7 and I am not able to get auditing to work.

There is nothing in the logs and /tmp is 777. I tried creating the log file manually and setting the owner to vault:vault.

We are on version 1.1.0. Could that be the issue?

What else can I try to get auditing working?
Is there an upgrade path to 1.16 from 1.1?

Thank you
