I am trialing the Perspective app on an iPad and Ignition 8 Beta on my laptop. When I’m on my home network I can launch apps on the iPad, when I am on my companies WiFi the app can’t reach the gateway. We were able to track this down to our firewall was blocking a port, we just don’t know which one. During our testing we simply disable the firewall and the devices started communicating. I had our IT team open the 8088 port, but that hasn’t fixed the issue. My question is, does the Perspective app communicate on a different port than 8088? ---

8088 should be all you need unless you’ve got SSL turned on. Make sure your firewall or router isn’t blocking our interfering with WebSocket traffic. ---
