Had the following issue that was resolved with a system reset but sharing the symptoms here in case it helps for anyone experiencing similar.
Device: naim uniti star
Issue: Spotify connect was not connecting to the naim. The naim was showing up in the available device list and showed a flashing “connecting” message but would then just time out after a minute or two without any further messaging or error info.
o tried on multiple client devices including android, IOS, and windows 10 with the same result.
o all other streaming services working fine including Tidal connect, chromecast, bluetooth, and apple airplay.
o performed a number of ‘resets’ including POR of the naim device, router reset, and reset all of my client side Spotify apps as per instructions on Spotify support website.
o using the naim remote and selecting Spotify from the menu on the naim device, I get the following message → “no user found. please login”
o client devices are on the same network as the naim device and able to ping the naim ip address from my client device
o naim and client firmware and network devices all up to date.
Solution: None of the above fixed the problem. But when I completed a naim factory reset on the uniti star, it cleared the issue. Not sure why a power on reset of the naim doesn’t reset all network interface settings but it is what it is. Hope this helps.
