Roam blocked
When plugged in, the red LED is steady
It can't be turned off, it can't be reset, it remains blocked.
Hello,
A solid red LED is not an expected status on Sonos LED lights
I would contact Sonos Support who may be able to review the diagnostic data to see the cause of the issue.

Bonjour,
Un voyant rouge fixe n'est pas un état attendu sur les voyants LED Sonos.
Je vous invite à contacter l'assistance Sonos, qui pourra peut-être examiner les données de diagnostic pour déterminer la cause du problème.
