After vSphere 6.0 upgrade - remote certificate is invalid

Sep 6, 2019

The Problem:

So you've upgraded your vSphere to version 6.0, but now you encounter a frustrating issue - the remote certificate is invalid. This issue can cause disruption to your virtual infrastructure and affect the proper functioning of your system. Don't worry, though, as ClubMaxSEO, a leading provider of SEO services for the Business and Consumer Services industry, is here to help you understand the problem and find the best solutions to get your vSphere up and running smoothly again.

Understanding the Issue:

When you see the "remote certificate is invalid" error message, it indicates a problem with the SSL/TLS certificate installed on your vSphere server. The certificate plays a crucial role in securing the communication between your vSphere environment and the external systems, such as your web browser. However, after the upgrade to vSphere 6.0, the certificate might become invalid or not trusted due to various reasons, potentially leaving your system vulnerable to security threats.

Potential Causes:

  • Expire or Incompatible Certificate: The original certificate might have expired or become incompatible with the new version of vSphere.
  • Incorrect Certificate Chain: The certificate chain might be misconfigured, leading to an invalid or untrusted certificate.
  • Self-Signed or Internal Certificates: Self-signed or internal certificates may not be recognized as trusted by external devices.
  • Security Enhancements: vSphere 6.0 introduced improved security measures, which may have stricter requirements for certificates.

Solutions and Prevention:

Solution 1: Check Certificate Validity and Compatibility

First, check the validity and compatibility of your SSL/TLS certificate. Verify if it has expired or if it is compatible with vSphere 6.0. If not, you may need to obtain a new certificate or update the existing one.

Solution 2: Ensure Correct Certificate Chain

Make sure the certificate chain is correctly configured. Check if all intermediate certificates are properly installed and linked to the root certificate. An incorrect certificate chain can result in an invalid or untrusted certificate.

Solution 3: Obtain a Trusted Certificate

If you are using self-signed or internal certificates, consider obtaining a trusted certificate from a well-known Certificate Authority (CA). Trusted certificates ensure that your communication is secure and trusted by most web browsers and external systems.

Solution 4: Update SSL/TLS Settings

In some cases, updating the SSL/TLS settings in your vSphere configuration may help resolve the remote certificate issue. Ensure that the appropriate protocols and ciphers are enabled, and any deprecated or weak configurations are disabled.
