@bigfellani5 It looks like you might be processing the queue through the phplist admin interface in the browser. That limits the elapsed sending time to 60s. this is to avoid problems with the browser or web server timing-out. You could try modifying the batch size, throttle, etc to fit in with that 60s limit.
It is generally more reliable to use a cron job to process the queue, which doesn’t have that limitation on the elapsed sending time.
