Hi @boubou,

How many Elasticsearch nodes do you have? It looks like you have a node communication issue based on this error:

> [@boubou](#):

> ` FATAL ResponseError: master_not_discovered_exception: [master_not_discovered_exception] Reason: null`

Can you try the remediation steps covered in [this StackOverflow thread](https://stackoverflow.com/questions/37970187/elasticsearch-cluster-master-not-discovered-exception)?

I see you have also raised a similar issue [here](https://discuss.elastic.co/t/elasticsearch-doesnt-work/350842). I would recommend following @DavidTurner's recommendation in thread to check out the troubleshooting guide,. Please don't post multiple topics for the same issue in future.

Hope that helps!
