Hi @Weemoose
Welcome to the Sonos Community!
When you say “re add the station”, do you mean you follow the instructions on our Add an Internet radio station to Sonos help page, or do you mean you just need to open the app and select the station again?
If the speaker has been rebooted, then the latter is expected behaviour. A system update will force a reboot, so this may have been what happened.
If the speaker ever spontaneously reboots (you’ll see a flashing white light for about 1 minute), this would be a problem, and you should get in touch with our technical support team directly.
I hope this helps.
