[PROBLEM] Spotify connect keeps dropping

[Tim Curtis]

Hi,

I see. That sounds like a bug in librespot. It shouldn't crash or exit due to interruption in connection, rather it should print a message and periodically try to reconnect.

I can compensate for that by implementing the watchdog code from earlier post but it needs to be modified to work correctly. See below.

/var/www/command/restart-spot.php

Code:

#!/usr/bin/php
