Hi Luca,
probably the elasticsearch didn’t start properly because of lack of resources.
In the instruction you were looking at we have:
"
Before starting the API Gateway please make sure that the main memory and the kernel settings of your docker host are correctly configured. The docker host should provide at least 4 GB of main memory. Since API Gateway comes with an Elasticsearch, the vm.max_map_count kernel setting needs to be set to at least 262144. You can change the setting on your docker host via the following command:
sysctl -w vm.max_map_count=262144
"
Did you do this?
