Dear Members, I have setup ECE for testing environment on 3 machines in different zone with IP as below 1XX.XXX.XXX.244, 1XX.XXX.XXX.245, 1XX.XXX.XXX.246 after setting up ECE i tried to integrate an elastic agent and used the certificate and downloaded from the ECE console and deployed the same certificate in fleet setting also. I am facing the error can someone please guide me enrollment attempt failed, retrying for 10m0s, every 1m0s enrolling to URL: [https://2077bdcea73cc171b2e.fleet.1XX.XXX.XXX.244.ip.es.io:9243/","ecs.version":"1.6.0](https://2077bdcea73cc171b2e.fleet.1XX.XXX.XXX.244.ip.es.io:9243/%22,%22ecs.version%22:%221.6.0)"} Error: fail to enroll: fail to execute request to fleet-server: x509: certificate is valid for 1XX.XXX.XXX.244, 1XX.XXX.XXX.245, \*[1XX.XXX.XXX.244.ip.es.io](http://1XX.XXX.XXX.244.ip.es.io), not [2077bdcea73cc171b2e.fleet.1XX.XXX.XXX.244.ip.es.io](http://2077bdcea73cc171b2e.fleet.1XX.XXX.XXX.244.ip.es.io) Best Regards, Shrikant ![image](https://us1.discourse-cdn.com/elastic/original/3X/4/3/435a70759d91e90bc1807d4e428dbd7db8584f2d.png) ---

This would likely involve generating a new certificate and updating it in your ECE and Fleet settings. or you could change the Fleet Server URL that the Elastic Agent is trying to connect to, so that it matches one of the domains or IP addresses the certificate is valid for.
