Description
When running in discovery mode, the daemon shows up in spotify, but fails to connect.
After this failure, the daemon is shown under "other networks" in spotify and then the connection works.

To Reproduce

1. Start the spotifyd with three network interfaces (at least in my case) and have it running in discovery mode
2. Click on 'Connect to device in spotify'
3. Select your daemon
4. Fails
5. Select the daemon under "other networks" and it works

Expected behavior
Don't switch the device in spotify.
