Qobuz connection failure and frequent disconnection

Using both the windows and the Android bluesound apps with a Node 2i, the apps will not connect to qobuz, often will connect after a 5, 10 or 15 minute delay, and then will lose the connection again after 10 mins, and the cycle repeats. This is not a problem when using the native Qobuz app, and restarting the router does not change this behaviour, so does not appear to be a problem with my router or with the qobuz servers.
