Encountering an “SSL certificate not trusted” error can be a significant concern for both website administrators and visitors. This error indicates that a web browser or client cannot establish a secure connection with a website due to issues with the SSL certificate. Such errors can undermine user trust and affect the overall security of your site. In this comprehensive guide, we will explore how to fix “SSL certificate not trusted” errors and how Lightyear Hosting can assist you in ensuring your SSL certificates are correctly configured and functioning.
Understanding the “SSL Certificate Not Trusted” Error
The “SSL certificate not trusted” error occurs when a browser cannot verify the authenticity or validity of an SSL certificate used by a website. This error typically manifests as a warning message that informs users of potential security risks. It’s crucial to address this issue promptly to maintain the credibility and security of your website.
Common Causes of the Error
- Expired SSL Certificate: An SSL certificate has a validity period, and if it expires, browsers will not recognise it as trusted.
- Self-Signed Certificate: Certificates issued by unverified or self-signed Certificate Authorities (CAs) are not trusted by most browsers.
- Untrusted Certificate Authority: If the SSL certificate is issued by a CA not included in the browser’s trusted CA list, it will be flagged as untrusted.
- Domain Name Mismatch: SSL certificates must match the domain they are issued for. A mismatch can trigger trust warnings.
- Incomplete Certificate Chain: An SSL certificate requires a complete chain of trust, including intermediate certificates. Missing intermediate certificates can cause trust issues.
- Revoked Certificate: If a certificate is revoked by the CA, it will no longer be considered valid.
Steps to Fix “SSL Certificate Not Trusted” Errors
1. Renew an Expired Certificate
Expired SSL certificates are one of the most common causes of trust errors. To resolve this:
- Check Expiration Date: Review the expiry date of your SSL certificate. You can use tools like SSL Checker to verify the certificate’s validity.
- Renew the Certificate: Contact your Certificate Authority (CA) to renew the expired certificate. Ensure that you complete the renewal process promptly to avoid security warnings.
- Install the New Certificate: Once renewed, install the updated certificate on your server to restore trust.
2. Obtain a Valid Certificate from a Trusted CA
Self-signed certificates and those issued by untrusted CAs are not recognised by browsers:
- Choose a Reputable CA: Obtain an SSL certificate from a well-known and trusted Certificate Authority. Popular CAs include DigiCert, Comodo, and GlobalSign.
- Install the Certificate: Follow the CA’s instructions for installing the new certificate on your server to ensure it is recognised as trusted.
3. Ensure Domain Name Matching
If there is a domain name mismatch, you need to:
- Verify Certificate Details: Check that the certificate’s common name (CN) and subject alternative names (SANs) match the domain you are accessing.
- Reissue the Certificate: If there is a mismatch, request a new SSL certificate with the correct domain names from your CA.
4. Install the Complete Certificate Chain
An incomplete certificate chain can cause trust issues:
- Obtain Intermediate Certificates: Ensure that you have all necessary intermediate certificates from your CA. These certificates help establish a full chain of trust.
- Install Intermediate Certificates: Follow your server’s instructions to install the complete certificate chain, including intermediate certificates.
5. Address Revoked Certificates
If your certificate has been revoked, you should:
- Replace the Certificate: Contact your CA to obtain a new certificate if your current one has been revoked.
- Update Your Server: Install the new, valid certificate on your server and remove any revoked certificates.
