# FAQ
## I've deleted/corrupted my repo and can't delete my app.
Argo CD can't delete an app if it cannot generate manifests. You need to either:
1. Reinstate/fix your repo.
1. Delete the app using `--cascade=false` and then manually deleting the resources.
## Why is my application still `OutOfSync` immediately after a successful Sync?
See [Diffing](user-guide/diffing.md) documentation for reasons resources can be OutOfSync, and ways to configure Argo CD
to ignore fields when differences are expected.
## Why is my application stuck in `Progressing` state?
Argo CD provides health for several standard Kubernetes types. The `Ingress`, `StatefulSet` and `SealedSecret` types have known issues
which might cause health check to return `Progressing` state instead of `Healthy`.
* `Ingress` is considered healthy if `status.loadBalancer.ingress` list is non-empty, with at least one value
for `hostname` or `IP`. Some ingress controllers
([contour](https://github.com/heptio/contour/issues/403)
, [traefik](https://github.com/argoproj/argo-cd/issues/968#issuecomment-451082913)) don't update
`status.loadBalancer.ingress` field which causes `Ingress` to stuck in `Progressing` state forever.
* `StatefulSet` is considered healthy if value of `status.updatedReplicas` field matches to `spec.replicas` field. Due
to Kubernetes bug
[kubernetes/kubernetes#68573](https://github.com/kubernetes/kubernetes/issues/68573) the `status.updatedReplicas` is
not populated. So unless you run Kubernetes version which include the
fix [kubernetes/kubernetes#67570](https://github.com/kubernetes/kubernetes/pull/67570) `StatefulSet` might stay
in `Progressing` state.
* Your `StatefulSet` or `DaemonSet` is using `OnDelete` instead of `RollingUpdate` strategy.
See [#1881](https://github.com/argoproj/argo-cd/issues/1881).
* For `SealedSecret`, see [Why are resources of type `SealedSecret` stuck in the `Progressing` state?](#sealed-secret-stuck-progressing)
As workaround Argo CD allows providing [health check](operator-manual/health.md) customization which overrides default
behavior.
## I forgot the admin password, how do I reset it?
For Argo CD v1.8 and earlier, the initial password is set to the name of the server pod, as
per [the getting started guide](getting_started.md). For Argo CD v1.9 and later, the initial password is available from
a secret named `argocd-initial-admin-secret`.
To change the password, edit the `argocd-secret` secret and update the `admin.password` field with a new bcrypt hash.
You can use a site like [https://www.browserling.com/tools/bcrypt](https://www.browserling.com/tools/bcrypt) to generate
a new hash. For example:
```bash
# bcrypt(password)=$2a$10$rRyBsGSHK6.uc8fntPwVIuLVHgsAhAX7TcdrqW/RADU0uh7CaChLa
kubectl -n argocd patch secret argocd-secret \
-p '{"stringData": {
"admin.password": "$2a$10$rRyBsGSHK6.uc8fntPwVIuLVHgsAhAX7TcdrqW/RADU0uh7CaChLa",
"admin.passwordMtime": "'$(date +%FT%T%Z)'"
}}'
```
Another option is to delete both the `admin.password` and `admin.passwordMtime` keys and restart argocd-server. This
will generate a new password as per [the getting started guide](getting_started.md), so either to the name of the pod (
Argo CD 1.8 and earlier)
or a randomly generated password stored in a secret (Argo CD 1.9 and later).
## How to disable admin user?
Add `admin.enabled: "false"` to the `argocd-cm` ConfigMap (
see [user management](operator-manual/user-management/index.md)).
## Argo CD cannot deploy Helm Chart based applications without internet access, how can I solve it?
Argo CD might fail to generate Helm chart manifests if the chart has dependencies located in external repositories. To
solve the problem you need to make sure that `requirements.yaml`
uses only internally available Helm repositories. Even if the chart uses only dependencies from internal repos Helm
might decide to refresh `stable` repo. As workaround override
`stable` repo URL in `argocd-cm` config map:
```yaml
data:
# v1.2 or earlier use `helm.repositories`
helm.repositories: |
- url: http://<internal-helm-repo-host>:8080
name: stable
# v1.3 or later use `repositories` with `type: helm`
repositories: |
- type: helm
url: http://<internal-helm-repo-host>:8080
name: stable
```
## I've configured [cluster secret](./operator-manual/declarative-setup.md#clusters) but it does not show up in CLI/UI, how do I fix it?
Check if cluster secret has `argocd.argoproj.io/secret-type: cluster` label. If secret has the label but the cluster is
still not visible then make sure it might be a permission issue. Try to list clusters using `admin` user (
e.g. `argocd login --username admin && argocd cluster list`).
## Argo CD is unable to connect to my cluster, how do I troubleshoot it?
Use the following steps to reconstruct configured cluster config and connect to your cluster manually using kubectl:
```bash
kubectl exec -it <argocd-pod-name> bash # ssh into any argocd server pod
argocd admin cluster kubeconfig https://<cluster-url> /tmp/config --namespace argocd # generate your cluster config
KUBECONFIG=/tmp/config kubectl get pods # test connection manually
```
Now you can manually verify that cluster is accessible from the Argo CD pod.
## How Can I Terminate A Sync?
To terminate the sync, click on the "synchronisation" then "terminate":
![Synchronization](assets/synchronization-button.png) ![Terminate](assets/terminate-button.png)
## Why Is My App Out Of Sync Even After Syncing?
Is some cases, the tool you use may conflict with Argo CD by adding the `app.kubernetes.io/instance` label. E.g. using
Kustomize common labels feature.
Argo CD automatically sets the `app.kubernetes.io/instance` label and uses it to determine which resources form the app.
If the tool does this too, this causes confusion. You can change this label by setting
the `application.instanceLabelKey` value in the `argocd-cm`. We recommend that you use `argocd.argoproj.io/instance`.
!!! note When you make this change your applications will become out of sync and will need re-syncing.
See [#1482](https://github.com/argoproj/argo-cd/issues/1482).
## Why Are My Resource Limits Out Of Sync?
Kubernetes has normalized your resource limits when they are applied, and then Argo CD has then compared the version in
your generated manifests to the normalized one is Kubernetes - they won't match.
E.g.
* `'1000m'` normalized to `'1'`
* `'0.1'` normalized to `'100m'`
* `'3072Mi'` normalized to `'3Gi'`
* `3072` normalized to `'3072'` (quotes added)
To fix this use diffing
customizations [settings](./user-guide/diffing.md#known-kubernetes-types-in-crds-resource-limits-volume-mounts-etc).
## How Do I Fix "invalid cookie, longer than max length 4093"?
Argo CD uses a JWT as the auth token. You likely are part of many groups and have gone over the 4KB limit which is set
for cookies. You can get the list of groups by opening "developer tools -> network"
* Click log in
* Find the call to `<argocd_instance>/auth/callback?code=<random_string>`
Decode the token at [https://jwt.io/](https://jwt.io/). That will provide the list of teams that you can remove yourself
from.
See [#2165](https://github.com/argoproj/argo-cd/issues/2165).
## Why Am I Getting `rpc error: code = Unavailable desc = transport is closing` When Using The CLI?
Maybe you're behind a proxy that does not support HTTP 2? Try the `--grpc-web` flag:
```bash
argocd ... --grpc-web
```
## Why Am I Getting `x509: certificate signed by unknown authority` When Using The CLI?
Your not running your server with correct certs.
If you're not running in a production system (e.g. you're testing Argo CD out), try the `--insecure` flag:
```bash
argocd ... --insecure
```
!!! warning "Do not use `--insecure` in production"
## I have configured Dex via `dex.config` in `argocd-cm`, it still says Dex is unconfigured. Why?
Most likely you forgot to set the `url` in `argocd-cm` to point to your ArgoCD as well. See also
[the docs](/operator-manual/user-management/#2-configure-argo-cd-for-sso).
## Why are `SealedSecret` resources reporting a `Status`?
Versions of `SealedSecret` up to and including `v0.15.0` (especially through helm `1.15.0-r3`) don't include
a [modern CRD](https://github.com/bitnami-labs/sealed-secrets/issues/555) and thus the status field will not
be exposed (on k8s `1.16+`). If your Kubernetes deployment is [modern](
https://www.openshift.com/blog/a-look-into-the-technical-details-of-kubernetes-1-16), ensure you're using a
fixed CRD if you want this feature to work at all.
## <a name="sealed-secret-stuck-progressing"></a>Why are resources of type `SealedSecret` stuck in the `Progressing` state?
The controller of the `SealedSecret` resource may expose the status condition on resource it provisioned. Since
version `v2.0.0` ArgoCD picks up that status condition to derive a health status for the `SealedSecret`.
Versions before `v0.15.0` of the `SealedSecret` controller are affected by an issue regarding this status
conditions updates, which is why this feature is disabled by default in these versions. Status condition updates may be
enabled by starting the `SealedSecret` controller with the `--update-status` command line parameter or by setting
the `SEALED_SECRETS_UPDATE_STATUS` environment variable.
To disable ArgoCD from checking the status condition on `SealedSecret` resources, add the following resource
customization in your `argocd-cm` ConfigMap via `resource.customizations.health.<group_kind>` key.
```yaml
resource.customizations.health.bitnami.com_SealedSecret: |
hs = {}
hs.status = "Healthy"
hs.message = "Controller doesn't report resource status"
return hs
```
