Spotify Connect shows wrong devices

[tim1234567]

Hi,

I have different/wrong devices in my connect list, even though I am on the same wifi with all devices, the Mac and the Phone see each other but I cannot see the Chromecast from my Mac. Instead thee is an old device which I havent used in months and have no access to anymore. BUT: If i start streaming from my phone the device shows up on the mac and I can even control the song but if I stop the play the device vanishes again.

How can I remove the not working / not existing device and add the available one (Chromecast)

What i tried:

• signing out and in again
• reinstalling (deleting application support and cache files)
• revoking access from offline devices in the user account settings

Plan
