I should start with the fact that the only recent change to my system is a new router from my internet provider, but there was not change to the IP addresses or model, etc. When I access the app through Roku, it's asking me to use a pin to connect. I created an Emby ID and password, and connected, but when I select my server, it gives me the 'Unable to Connect' error. The MediaCenter is running at the time of the error.
On the computer, it shows my Samsung TV as the only active device. What am I missing?
