@juanshishido: This error started again on 2017-10-21 00:00 UTC and the last one was on 2017-10-24 21:50 UTC. I have just re-run the cronjob that gets the report data and no errors appeared this time. If they reappear I will post here.
Thank you!

Oh, thank you for that confirmation, @juanshishido! It crossed my mind it might have been something like that.
