Hi Jole, thank you for reaching out.

Would you be able to show your plugin-security.policy for x-pack-watcher ?  
Most likely it would be in "/usr/share/elasticsearch/modules/x-pack-watcher"

Could you also point to a place where you got your JDK from?

Please add following line  
`-Djava.security.debug=access,failure`  
to your elasticsearch jvm.options `/etc/elasticsearch/jvm.options`  
And then provide us with logs from `sudo journalctl -u elasticsearch`

Possibly the problem described by a user here might be similar to yours:
