I’ve deployed the admin-backend on our test Kubernetes cluster, below is the manifest file content:

```javascript

```

I can confirm that the backend is now up and running, please check screenshot:

However it’s seems to me the Backend is not yet picked up correctly in the web UI:

I’ve looked up all available documents on this topic but could not find any info on how Forest Admin website system authenticate with the admin backend.

It would be great if any developer or support staff could guide me to the right place for answers.

Many thanks in advance

@GuillaumeGautreau I’ve managed to fix the issue on my end. The issue is with the `APPLICATION_PORT` which I set to `3310`, however my exposed `APPLICATION_HOST` is `https://REDACTED` which uses port 443. To fix that I update my manifest file so that:

```javascript
        - name: APPLICATION_HOST
          value: 'https://REDACTED'
        - name: APPLICATION_PORT
          value: '443'

```
