      Steps to Reproduce:

      1. Deploy 4.14 cluster with OpenShiftSDN
      2.  Deploy NOO 1.10 and 0-click loki Create FC with Loki enabled in monolithic mode
      3. Check network traffic page with Loki as datasource
      

      Actual results:

      Flows are not sent to FLP

      Expected results:

      flows should be sent
      

      Workaround:
      To disable Network Policy for 1.10 in flowcollector
