SpotifyConnect "Failed to register IPv6 receiver"

[DevZky]

Hello, after reinstall my volumio device I am able to find the volumio in the list of my Spotify-Connect Devices, but it's greyed out and no connection is possible. Here's the corresponding log data:

Hopefully somebody is facing the same issue and a solution is out there ^^! Changing the option from HW to SW in mixer settings doesn't help.

Failed to register IPv6 receiver is just a warning, as volumio disables IPv6 by default. Can you try to turn off multi-device and add your credentials to rule out issues in your network setup?

Thank you very much for the quick answer. I could swear I have already tried MultiUser-Device on/off, anyway. After turn MultiUser-Device off and typing in my user data it's working, even after I turned MultiUser-Device back on again!

I cleared the link to "Vollibrespot" in "spotify.com > Spotify-Account > Apps". It seems a reinitialisation of "Vollibrespot" was necessary?! Maybe, maybe not. :)

Wow, after an hour I found this issue. Seems that reinitialisation is necessary (I changed HifiberryOS to Volumio)
