Spark(Openfire) Plugins HTTP File upload download error

I’m trying to install HTTP File upload on Spark(Oenfire) server, but I can’t install it because the network is closed. Is there an IP and Port that should be allowed?


“To change the HTTP server port from the default value (7443) used by Openfire, the property plugin.httpfileupload.announcedWebPort can be set to new value.”
