Cannot Install Fleet Server

Hello there,

Server info:
1 - I´m running ubuntu server 18.04
2 - Elk stack running on 7.13 version

fleet server creation does not work.

root@elastic:/tmp/agent/elastic-agent-7.13.1-linux-x86_64# sudo ./elastic-agent install -f --fleet-server-es=https://localhost:9200 --fleet-server-service-token=AAEAAWVsYXN0aWMvZmxlZXQtc2VydmVyL3Rva2VuLTE2MjI4NzA5NjA3NjU6aDN4dUQ1Y2NUYmFyZ2VkYUFiQXBKUQ --fleet-server-es-ca=/etc/elasticsearch/elastic-certificates.p12
The Elastic Agent is currently in BETA and should not be used in production

Error: fleet-server never started by elastic-agent daemon: context canceled
Error: enroll command failed with exit code: 1

Inside the data/elastic-agent-{hash}/ logs directory, there should be some logs from the fleet-server itself. Any chance you could share these?
