Updated: Feb 21, 2026
Technical Meaning
This error code indicates that a DNS operation was completed, but no trust anchors were added because all received trust anchors were either invalid, unsupported, expired, or would not become valid within the next 30 days.
Error Details
The trust anchors are critical components in validating the authenticity of DNS responses. They are used to establish a chain of trust for DNSSEC (Domain Name System Security Extensions) enabled zones. When these trust anchors cannot be validated, it can lead to potential security risks and unreliable DNS resolution.
Usage Context
This error typically occurs during operations that require validation of DNSSEC records, such as resolving domain names or validating the authenticity of DNS responses. It is important for developers to ensure that their applications handle this scenario appropriately to maintain system integrity and security.
Developer Interpretation
When encountering this error, developers should focus on ensuring that all trust anchors provided are valid, supported, and within their validity period. This may involve verifying the source of the trust anchors or adjusting the configuration settings to include only valid and current anchors.
