Load Balancers LoadBalancerSSLHandshakeErrors

There are errors during SSL handshakes, possibly due to misconfigured certificates.

Understanding Load Balancers

Load balancers are critical components in modern web infrastructure. They distribute incoming network traffic across multiple servers, ensuring no single server becomes overwhelmed, which helps in maintaining high availability and reliability of applications.

Symptom: LoadBalancerSSLHandshakeErrors

When monitoring load balancers with Prometheus, you might encounter the alert LoadBalancerSSLHandshakeErrors. This alert indicates that there are errors occurring during SSL handshakes, which can disrupt secure communications between clients and servers.

Details About the LoadBalancerSSLHandshakeErrors Alert

The LoadBalancerSSLHandshakeErrors alert is triggered when there are issues in establishing a secure SSL/TLS connection. This typically happens due to misconfigured SSL certificates, expired certificates, or unsupported SSL/TLS versions. Such errors can prevent clients from securely connecting to your services, leading to potential data breaches or service disruptions.

Common Causes of SSL Handshake Errors

  • Expired or invalid SSL certificates.
  • Incorrect SSL certificate chain configuration.
  • Unsupported SSL/TLS protocol versions.
  • Network issues causing incomplete handshakes.

Steps to Fix LoadBalancerSSLHandshakeErrors

To resolve SSL handshake errors, follow these steps:

Step 1: Verify SSL Certificate Validity

Ensure that your SSL certificates are valid and not expired. You can check the certificate details using the following command:

openssl s_client -connect yourdomain.com:443 -servername yourdomain.com

Look for the certificate expiration date and ensure it is valid.

Step 2: Check SSL Certificate Chain

Ensure that the SSL certificate chain is correctly configured. You can use online tools like SSL Labs to test your SSL configuration and identify any chain issues.

Step 3: Update SSL/TLS Protocols

Ensure that your load balancer supports the latest SSL/TLS protocols. Update your configuration to disable outdated protocols like SSLv3 and enable TLSv1.2 or TLSv1.3.

Step 4: Monitor and Test

After making changes, monitor your load balancer logs for any recurring handshake errors. Use tools like cURL to test connections:

curl -v https://yourdomain.com

Conclusion

By following these steps, you can effectively diagnose and resolve LoadBalancerSSLHandshakeErrors. Regularly updating and monitoring your SSL configurations will help maintain secure and reliable connections for your applications.
