Version-Release number of selected component (if applicable):

* OCP versions:
  - Source cluster: OCP3.11
  - Target cluster: OCP4.2.0

* CAM
  - rhcam-1-0

How reproducible:

CU said this issue has been started to happen after stopping both cluster for 1 day and start both ones again.

1. Stopped source and target clusters for 1 day.

2. The connection failure with following messages and you should add again a source cluster with service account token.

~~~
Connection failed. Message: "Test connect failed: Get https://console.ocp.example.com:8443/api?timeout=5s: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)", Reason: "ConnectFailed"
~~~

3. After adding a source cluster successfully again, when you add "Plan" to migrate, the error message is shown in WEB UI.

~~~
Reconcile failed: [no matches for kind "ImageStream" in version "image.openshift.io/v1"]. See controller logs for details.
~~~

Steps to Reproduce:
1.
2.
3.

Actual results:
