Authentication, Network & Node.js Environments

CLI authentication fails with a "Login Error {}" response despite the web portal authentication succeeding.

Root cause

A compatibility issue exists between the Contentstack CLI and Node.js versions 22.13.1 and 22.14.1, which causes authentication failures.

Resolution

1. Verify your current Node.js version using the command node -v.
2. Downgrade to Node.js 20.18.
3. Re-attempt your CLI login.

CLI authentication completes successfully after downgrading to the supported Node.js version. After completing these steps, attempt to authenticate into the CLI again. If the issue persists, escalate with your CLI version and current environment details.

A "self-signed certificate in certificate chain" error occurs during CLI authentication via SSO, preventing successful login.

Root cause

The error is caused by a failure in the environment-side trust path, typically resulting from corporate proxies, SSL inspection, or missing enterprise root Certificate Authorities (CAs).

Resolution

1. Work with your internal IT or security team to add the enterprise root CA certificate to your system's trusted store.
2. Alternatively, as a temporary workaround, disable SSL verification by running the command: npm config set strict-ssl false.

Authentication proceeds successfully once the certificate trust path is established or SSL verification is temporarily disabled. After completing these steps, attempt the CLI login again. If the issue persists, escalate with your system's security configuration details and the specific error output.

CLI authentication fails despite following official documentation, indicating an environment-specific configuration issue.

Root cause

The failure is caused by local configuration, network policies, or system-level restrictions specific to the machine or network environment.

Resolution

1. Verify the CLI version and login method being used.
2. Test the login on a different machine to isolate the issue to your specific environment.
3. If login succeeds on another device, work with your internal IT team to review local firewall rules, proxy configurations, enterprise network restrictions, and system-level authentication blocks.

CLI login functions as expected once environment-level network and security restrictions are resolved. After completing these steps, attempt the CLI login again. If the issue persists, escalate with your system's network configuration details and any error logs generated during the authentication process.

CLI command execution failures occur when running Contentstack CLI on Node.js versions higher than 22.2.0.

Root cause

Specific incompatibilities exist between the Contentstack CLI and Node.js versions exceeding 22.2.0, which prevent commands from executing.

Resolution

1. Verify your current Node.js version by running node -v.
2. If you are running a version higher than 22.2.0, downgrade to Node.js 22.2.0 or a stable Long Term Support (LTS) version below it.
3. Subscribe to the Contentstack CLI changelog to monitor updates and compatibility fixes.

CLI commands execute successfully once your environment is configured to a compatible Node.js version. After completing these steps, re-run your CLI commands to verify functionality. If errors persist, ensure your CLI is up to date and check the release notes for any newer compatibility patches.

CLI commands fail with authentication errors during stack operations.

Root cause

The failure is caused by an invalid, expired, revoked, or incorrectly generated authentication token that lacks the necessary permissions to execute the requested command.

Resolution

1. Verify that your current Management Token or authentication token is valid and has not expired.
2. Generate a new Management Token if you suspect the existing token is invalid, revoked, or lacks necessary permissions.
3. Update your CLI configuration with the new token using csdx auth:tokens:add.
4. Re-run the command to confirm successful authentication.

CLI commands execute successfully once a valid token with appropriate permissions is configured. After completing these steps, attempt your stack operations again to verify that the authentication error is resolved. If the issue persists, ensure that the newly generated token has the correct scope and permissions assigned within the stack settings.

CLI authentication fails despite correct regional and account configurations, due to network interference from VPNs.

Root cause

The failure is caused by VPN interference, which blocks authentication traffic, prevents proper network pathing, or enforces policies that prevent the CLI from connecting to the authentication service.

Resolution

1. Verify that your configured Contentstack region matches your account settings.
2. Ensure your CLI is updated to the latest available version.
3. If authentication fails, temporarily disable your VPN to rule out network path or policy-based traffic blocks.

CLI authentication proceeds as expected once the VPN is disabled or the network path is cleared of interference. After completing these steps, attempt the CLI login again to verify the fix. If login still fails, inspect your firewall or corporate security settings for further network traffic restrictions.
