Hey guys,

we are facing some troubles with our Rancher:

**Our Setup**

- RKE-Cluster: v1.2.10
- Rancher: v2.6.1 (installed via official Helmcharts)

Our Rancher is running on a dedicated RKE-Cluster.

**Projects/Namespaces \> MyProject**

We want to add a user to a Project “MyProject”. After Click on “Save”, the user was not successful saved.  
The following route “[https://rancher.local/v3/projectroletemplatebindings](https://rancher.local/v3/projectroletemplatebindings)” returns HTTP500-Error

`{"baseType":"error","code":"InternalError","message":"Internal error occurred: failed calling webhook \"rancherauth.cattle.io\": Post \"https://rancher-webhook.cattle-system.svc:443/v1/webhook/validation?timeout=10s\": x509: certificate has expired or is not yet valid: current time 2021-10-22T11:54:09Z is after 2021-10-12T11:47:20Z","status":500,"type":"error"}`

We tried the following steps to resolve the problems:

- Rancher-GUI: **Cluster Management \> MyCluster \> Rotate Certificate** =\> no success
- RKE-Cluster: `rke cert rotate` =\> no success

The dirty quick fix was, change the date and time before SSL-Cert expired. But this caused a lot of other problems.

Right now, our Rancher is not fully usable.

Anyone some ideas?
