I have an app that I submitted to the app store. The app connects to our server on port 8081, we have tested this app
in several different locations to make sure it is working. We tested on different Wifi and cellular connections and all is working.
The app got rejected for the reason it can't connect to the server. I mentioned to the reviewer if they have a firewall
it may be blocking that specific port, but they still can't connect.
Any suggestions that may help would be appreciated.
