Sonos Roam - Failed Login!

I’m running HA 2024.4.0 with the SONOS integration. There are five speakers identified by the integration. Each shows on-line and are controllable from the integration.

This morning I wake up to an HA notification;

Login attempt failed
Login attempt or request with invalid authentication from sonoszp.lan (192.168.86.91). See the log for details.

I don’t understand why this notification is appearing. I’ve checked all the logs I can find. No mention of this device anywhere. The Sonos Support page shows all speakers. When I drill down on the Sonos Roam there is an error showing under the [/proc/ath_rincon/status](javascript:toggle(‘id6’)) path. The error reads;

contents of /proc/ath_rincon/status
error opening file /proc/ath_rincon/status (errno=2 No such file or directory)

I’m not blaming the 2024.4.0 update however it seems the problem started following completion of that update.

I don’t understand the error or how to stop the notification from occurring. Any assistance you can offer in this regard would be appreciated.

Problem found!
