Connection timeout error when adding a Git repository in Adobe Experience Manager Cloud Manager

Last update: October 5, 2026

In Adobe Experience Manager Cloud Manager, a connection timeout error can occur when you add a Git repository for build automation. The repository addition process fails because Cloud Manager can’t establish a connection to the repository. To fix this issue, make the repository accessible to Cloud Manager and allowlist the required Adobe IP addresses.

Description description

Environment

Adobe Experience Manager (AEM) Cloud Manager (all versions)

Symptoms

  • Error message: “Connection to the repository timed out. This may indicate the service is behind a firewall or not responding. Please ensure the service is reachable and contact support to allowlist the required IPs if needed.”
  • The repository is accessible only from internal networks or through a VPN.
  • The connection fails during the repository addition process in Cloud Manager.

Cause

The timeout occurs because Cloud Manager can’t access the Git repository when it isn’t reachable from the public internet or when the required Adobe Cloud Manager IP ranges aren’t allowlisted on the firewall or security gateway.

Resolution resolution

Follow the steps below to resolve the issue.

  1. Ensure that your Git repository endpoint is accessible from the public internet. Cloud Manager can’t connect to repositories that are available only on internal networks or through a VPN.
  2. On your firewall or security gateway, allow incoming connections from the current Adobe Cloud Manager egress IP ranges. These IP ranges are required for Cloud Manager to reach your repository.
  3. Refer to the official Adobe documentation for the latest list of Cloud Manager egress IP addresses. The list can change over time. You can find the current IP ranges in the Cloud Manager documentation under the section for adding external repositories.
  4. Confirm that outbound HTTPS (port 443) traffic is allowed from Cloud Manager to your Git repository endpoint.
  5. Ensure that any required proxy, DNS, or TLS configurations are correctly set up to permit access from Cloud Manager.
  6. After updating your firewall rules and network configuration, try adding the repository again in Cloud Manager.
  7. If the connection still fails, review your firewall logs for any blocked connections from the Adobe Cloud Manager IP ranges and verify that all network prerequisites are met.
