I am managing an environment that is beginning to lock down on all their applications on the network and need to make sure the ports that QVS uses are open. I have seen this answer (https://community.qlik.com/thread/46096) which seems to deal mostly with ports internally, but which ports would I need to check for external use? Specifically I need to make sure the port which the license key is sent from the server to Qlik is open. How exactly does Qlik verify a new server license if it is updated or brand new?
