+### Disable IPV6
+Starting with AWX Operator release 0.24.0,[IPV6 was enabled in ngnix configuration](https://github.com/ansible/awx-operator/pull/950) which causes
+upgrades and installs to fail in environments where IPv6 is not allowed. Starting in 1.1.1 release, you can set the `ipv6_disabled` flag on the AWX
+spec. If you need to use an AWX operator version between 0.24.0 and 1.1.1 in an IPv6 disabled environment, it is suggested to enabled ipv6 on worker
+nodes.
+
+In order to disable ipv6 on ngnix configuration (awx-web container), add following to the AWX spec.
+
+The following variables are customizable 
+
+| Name          | Description            | Default |
+| ------------- | ---------------------- | ------- |
+| ipv6_disabled | Flag to disable ipv6   | false   |
+
+```yaml
+spec:
+  ipv6_disabled: true
+```

 ### Adding Execution Nodes
 Starting with AWX Operator v0.30.0 and AWX v21.7.0, standalone execution nodes can be added to your deployments.
 See [AWX execution nodes docs](https://github.com/ansible/awx/blob/devel/docs/execution_nodes.md) for information about this feature.
