LMS not finding any players

[agent_kith]

Are there any basic plugins or enablers that need to be set up?  Diagnioctics / checks to to?

Only reason I can think of is you have multiple copies of LMS running. And the squeezelite you're running just so happens to connect to the other instance.

If you already have LMS running somewhere else, disable server players, and just start Squeezelite on the Pi, and that will be perfect. In theory the LMS Web link will still be able to detect any LMS on the same network.

If you want to run multiple LMS, note the LMS discovery code will only return you the first LMS that respond to Snakeoil, and it may not return you the LMS you're looking for. In this case you just need to enter the IP manually and it'll work.
