  <definition term="I’m trying to create a Cloud organization, but I’m already part of a different one.">
    Users can only belong to one Elastic Cloud organization at a time. If you want to create or join another organization, you must [leave the previous one](/docs/cloud-account/join-or-leave-an-organization#ec-leave-organization) or use a different email address.
  </definition>
  <definition term="I need to uninstall Elastic Agent.">
    Refer to [Uninstall Elastic Agent](https://www.elastic.co/docs/solutions/security/configure-elastic-defend/uninstall-elastic-agent) for instructions.
  </definition>
  <definition term="My cluster was disconnected from Elastic Cloud and I want to reconnect it.">
    If the cluster was disconnected by one of the users in your Cloud organization, you can repeat the [installation process](https://www.elastic.co/docs/deploy-manage/monitor/autoops/cc-connect-self-managed-to-autoops) to reconnect. If not, explore [additional resources](/docs/troubleshoot#troubleshoot-additional-resources) or [contact us](/docs/troubleshoot#contact-us).
  </definition>
  <definition term="After running the installation command, I can't move on to the next steps.">
    If an error appears on the screen, follow the suggestion in the error message and try to run the command again. If the issue is not resolved, explore [additional resources](/docs/troubleshoot#troubleshoot-additional-resources) or [contact us](/docs/troubleshoot#contact-us).
  </definition>
  <definition term="My organization's firewall may be preventing Elastic Agent from collecting and sending metrics.">
    If you're having issues with connecting your cluster to AutoOps and you suspect that a firewall may be the reason, refer to [Troubleshoot firewalls blocking Elastic Agent](https://www.elastic.co/docs/deploy-manage/monitor/autoops/autoops-sm-troubleshoot-firewalls).
  </definition>
  <definition term="Elastic Agent is failing to connect because it doesn't recognize my SSL certificate.">
    If Elastic Agent is failing to connect your cluster to AutoOps because it doesn't recognize your SSL certificate, refer to [Configure AutoOps Elastic Agent with a custom SSL certificate](https://www.elastic.co/docs/deploy-manage/monitor/autoops/autoops-sm-custom-certification).
  </definition>
  <definition term="I went through the wizard with Elastic Cloud on Kubernetes (ECK) as my installation method, but I can't view any connected clusters in my account. Elastic Cloud on Kubernetes: Generally available since 3.3">
    Refer to [Troubleshoot connected clusters not appearing with ECK installation](https://www.elastic.co/docs/deploy-manage/monitor/autoops/autoops-sm-troubleshoot-eck-no-clusters) to diagnose and resolve common issues.
