Tidal App - Bluesound speakers not showing up

After about a year of usage with minimal issues, my Bluesound speakers are no longer accessible through the Tidal or Spotify app (the Bluesound app is fine). This has been going on for about a month or so. Does anyone have this problem and/or know how to fix it?

My setup:

Pulse Flex 2i - Wifi

Mini - Wifi

Node module in NAD amp - ethernet

Network is on Centurylink and it's plenty fast.
