I can see :

{"reqId":"KL8cdy7oSn4OJmcc5Sv9","remoteAddr":"10.115.64.145","app":"core","message":"Could not get application: cURL error 6: Could not resolve host: api.owncloud.com; Name or service not known","level":3,"time":"2016-10-14T12:52:12+00:00","method":"GET","url":"\/owncloud_9_1_1\/cron.php","user":"--"}

Very strange because owncloud seems to work correctly.
