To help alleviate these issues, you can run the [adjust-downstream-webhook](https://github.com/rancherlabs/support-tools/tree/master/adjust-downstream-webhook) shell script after roll back. This script selects and installs the proper webhook version (or removes the webhook entirely) for the corresponding Rancher version.

The following affects Rancher v2.8.3 and v2.8.4.
When a Rancher-Webhook deployment is unpinned, it can be automatically updated to a version that is incompatible with the current version of Rancher. This is a known issue for Rancher versions 2.8.3 and 2.8.4. The solution is to *pin* the appropriate version. The following table shows which webhook version to provide for each respective version of Rancher:

For example, if you are running Rancher v2.8.3, you need to pin Rancher-Webhook to version 103.0.2+up0.4.3.
Note that if you view the Local cluster in Rancher, and then bring up `Workloads | Deployments`, selecting at least `System Namespaces`, you should see a `rancher-webhook` workload in the `cattle-system` namespace. It will probably have an associated version, but this isn't sufficient to determine if the webhook is pinned to a specific version.

For helm installations, there are two ways to pin the webhook. If you're using a values file, you would add this block to a YAML file (often called `values.yaml`) to pin the webhook when using Rancher 2.8.3:

If you're running `rancher` via a `docker` installation, you need to stop and delete the `rancher/rancher` container, and then rerun the `docker run` command, adding the command-line options `--env CATTLE_RANCHER_WEBHOOK_VERSION=<WEBHOOK-VERSION>` somewhere before `rancher/rancher:<VERSION>`.
