             Summary: NiFi 1.15.2 -- GUI freezing when remote process group loses connection
                 Key: NIFI-10526
                 URL: https://issues.apache.org/jira/browse/NIFI-10526
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core UI
    Affects Versions: 1.15.0
         Environment: Redhat 7.9
            Reporter: Evan Falkenstine


When my Remote Process Groups lose connection to the distant end the NiFi GUI freezes and won't let me stop/start processors or create new objects. I'm able to interact with the GUI such as context menus but none of the actions go through. I can use the context menu to disable the RPG but it takes 10-15 minutes for the disable action to apply, lining up with the rest of the GUI "unlocking". Restarting NiFi does not help to break the connection enough because during bootup it starts the connection attempt before I can stop the RPG. I've had success with editing the flow.xml.gz file and changing the RPG to disabled and restarting NiFi. This happens 100% of the time on NiFi 1.15.2.
