The problem

The DLNA player provider appears to become unstable after a long period of time, throwing the following errors in the logs.

When these errors are thrown, any players that are available on the network seem to become completely unavailable with a loading symbol next to the player itself.

Reloading the player provider will pickup the players again for a brief period, but after 10 seconds or so, they all disappear again.

How to reproduce

1. Setup DLNA with scan network enabled
2. Wait for a long time (maybe? I restarted MA and the problem went away, MA has been up pretty much since the latest beta release).

N/A issue impacts the player provider, music providers still work fine
