Hello,
I do not have the commands with which I performed the installation.
The certificates are intact, only the agent was rewritten in the previous version when instead of updating I gave install, since this began to present the problem.
I need the agent that is in the fleet server to enroll again so that the other agents are online.
I generated a new service token
I share what I have executed and the errors that I see at the moment.
sudo /opt/elastic-agent-8.18.1-linux-x86_64/elastic-agent install \
--url="https://172.26.6.39:5601" \
--fleet-server-es="https://172.26.6.37:9200" \
--fleet-server-service-token="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" \
--fleet-server-policy="fleet-server-policy" \
--fleet-server-es-ca-trusted-fingerprint="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" \
--fleet-server-host="172.26.6.41" \
--fleet-server-port=8220 \
--fleet-server-cert="/etc/certs/elacluster/fleetserver.crt" \
--fleet-server-cert-key="/etc/certs/elacluster/fleetserver.key"
Elastic Agent will be installed at /opt/Elastic/Agent and will run as a service. Do you want to continue? [Y/n]:Y
