Internet down, Roon won't play my local files, can't log on

Hi @andrew_sell,

You have our sincere apologies for the inconvenience here. There’s some more discussion on this in this post:

Basically, the initial login does require an internet connection, but once you’re logged in you can go for weeks without an internet connection. If you’re not currently logged in, you could use something like hotspot for the login, but after that you can go for quite a while without the need for an internet connection.
