Logs

Not sure if related but there are multiple logs:

time="2020-08-04T09:45:39Z" level=error msg="Failed to detect if self-signed certificate used. Cause: routes.route.openshift.io \"test\" already exists"
time="2020-08-03T20:11:32Z" level=error msg="Failed to create test route 'test': routes.route.openshift.io \"test\" already exists"

might be broken due to test route creation:

	if len(endpointURL) < 1 {
		// Create test route to get certificates chain.
		// Note, it is not possible to use SyncRouteToCluster here as it may cause infinite reconcile loop.
		routeSpec, err := GetSpecRoute(instance, "test", "test", 8080, clusterAPI)
		if err != nil {
			return nil, err
		}

Installation method

• OperatorHub

@ibuziuk that’s a good question. it is better to apply the same fix for 7.16.x branch.

Scale down/up che-operator deployment. Eclipse Che will start deploying from the beginning.
