Lab 2.1: Added Nginx Integration/Agent but Kibana/Discover is empty

it worked:
(elastic) elastic@ip-172-31-38-81:~$ sudo /opt/Elastic/Agent/elastic-agent uninstall
Elastic Agent will be uninstalled from your system at /opt/Elastic/Agent. Do you want to continue? [Y/n]:Y
Elastic Agent has been uninstalled.

no need to open a new ticket :wink:
Thanks.
