To fix the issue:
- Log in to your Lifecycle Services (LCS) project and locate the cloud-hosted environment.
- Choose "Rotate SSL certificate" and confirm the action. This process will restart your environment.
- The operation will be displayed in LCS and may take some time to complete. You can monitor its progress in the environment details.
- Once the operation is complete and the environment is back online, try accessing the D365FO instance again.
Important Note: Rotating SSL certificates will restart your environment, so ensure you save any unsaved work before initiating this process.
