Hi. The Flic hub and the Hue hub must be on the same LAN network in order to see each other. Make sure they are behind the same router.

@marook Which kind of Sonos device do you have? The ones we test with at the office are Sonos Play: 1.

@nadia Is this something that will be addressed?

@ap-iotbutton That means that TLS certificate validations are skipped, which should only be used for self-signed certificates that the system normally doesn't trust. Can you please tell me the domain name of the website you try to connect to, so we can check if a root certificate is missing?
