API endpoints are not being refreshed

Hello, I noticed the API endpoints (e.g. [/all](https://covid-19-greece.herokuapp.com/all) ) have stopped refreshing since the 14th of April. The data is still coming in on github though, for example [here](https://github.com/Covid-19-Response-Greece/covid19-greece-api/blob/master/data/greece/general/timeseries_greece.json).
