Verify failed because all jwks size provided JWKs were filtered – How to solve this Elasticsearch exception

August-23, Version: 8.4-8.9

Briefly, this error occurs when Elasticsearch’s security feature is unable to verify the JSON Web Key Set (JWKS) provided for JSON Web Tokens (JWT) authentication. This could be due to incorrect or incompatible keys. To resolve this issue, you can 1) Check the JWKS provided for any errors or inconsistencies. 2) Ensure the keys are compatible with the JWT authentication. 3) Update or regenerate the keys if necessary. 4) Check the filtering criteria, as it might be too restrictive, causing all keys to be filtered out.

Log Context

Log “Verify failed because all ” + jwks.size() + ” provided JWKs were filtered.” class name is We extracted the following from Elasticsearch source code for those seeking an in-depth context :

 final List jwksStrength = -> JwkValidateUtil.isMatch(j; alg.getName())).toList();
 LOGGER.debug("JWKs [{}] after Algorithm [{}] match filter."; jwksStrength.size(); alg);  // No JWKs passed the kid; alg; and strength checks; so nothing left to use in verifying the JWT signature
 if (jwksStrength.isEmpty()) {
 throw new ElasticsearchException("Verify failed because all " + jwks.size() + " provided JWKs were filtered.");
 }  for (final JWK jwk : jwksStrength) {
 if (jwt.verify(createJwsVerifier(jwk))) {
