New Relic Agent The New Relic Agent is unable to establish a secure connection due to SSL certificate issues.

The SSL certificate may be invalid, expired, or incorrectly installed, preventing the New Relic Agent from establishing a secure connection.

Understanding New Relic Agent

New Relic Agent is a powerful tool designed to monitor and manage application performance. It provides real-time insights into application behavior, helping developers identify bottlenecks and optimize performance. By collecting and analyzing data, the agent helps ensure applications run smoothly and efficiently.

Identifying the Symptom

When using the New Relic Agent, you might encounter an error message indicating an SSL Certificate Error, specifically NR-1008. This error suggests that the agent is unable to establish a secure connection due to SSL issues. As a result, data transmission between your application and New Relic's servers is disrupted.

Common Observations

  • Connection failures or timeouts when the agent attempts to communicate with New Relic servers.
  • Error logs indicating SSL handshake failures.

Exploring the Issue: NR-1008

The NR-1008: SSL Certificate Error occurs when the New Relic Agent cannot verify the SSL certificate presented by the server. This can happen due to several reasons, such as an expired certificate, a certificate not trusted by the agent, or incorrect installation of the certificate on the server.

Potential Causes

  • The SSL certificate has expired or is not yet valid.
  • The certificate chain is incomplete or improperly configured.
  • The certificate is self-signed and not recognized by the agent.

Steps to Resolve the SSL Certificate Error

To resolve the NR-1008 error, follow these steps:

1. Verify the SSL Certificate

Ensure that the SSL certificate is valid and correctly installed on your server. You can use online tools like SSL Labs to check the certificate's validity and configuration.

2. Update the New Relic Agent

Ensure that you are using the latest version of the New Relic Agent, as updates may include fixes for SSL-related issues. You can check for updates and upgrade the agent by following the instructions in the New Relic documentation.

3. Check Certificate Chain

Ensure that the certificate chain is complete and correctly configured. This includes the root certificate, intermediate certificates, and the server certificate. You can use the openssl command to verify the chain:

openssl s_client -connect yourserver.com:443 -showcerts

4. Configure Trusted Certificates

If you are using a self-signed certificate, add it to the trusted certificates store of the New Relic Agent. Refer to the New Relic SSL configuration guide for detailed instructions.

Conclusion

By following these steps, you should be able to resolve the NR-1008: SSL Certificate Error and restore secure communication between your application and New Relic servers. Regularly updating your SSL certificates and the New Relic Agent will help prevent similar issues in the future.
