I am using port 8080 on the Roku devices to integrate the Roku box with my smart home system. It works well for a long period of time, and then all of a sudden it will stop responding to connection requests on port 8080 completely.
A port scan on the device, at this point, indicates that all ports are filtered, and that no ports are open. A reboot of the device does not fix the issue, a reset however, does. At which point, I have to enter everything back into the device.
This is absolutely maddening, and unacceptable.
