I have configured the ssl certificate for my es, but when I want to reset the password, this exception occurs. I am sure that the" **kunboy5240.tk**" in the url I entered is my domain name used to generate the certificate , why is such an exception reported:

```auto
org.elasticsearch.common.ssl.DiagnosticTrustManager - failed to establish trust with server at [kunboy5240.tk]; the server provided a certificate with subject name [CN=instance], fingerprint [6d09b19661cf05f7c93c2cde2b02e824582e974b], no keyUsage and no extendedKeyUsage; the session uses cipher suite [TLS_AES_256_GCM_SHA384] and protocol [TLSv1.3]; the certificate does not have any subject alternative names; the certificate is issued by [CN=Elastic Certificate Tool Autogenerated CA]; the certificate is signed by (subject [CN=Elastic Certificate Tool Autogenerated CA] fingerprint [f77c65e09106ec599b9524d8a90d15237d33db83] {trusted issuer}) which is self-issued; the [CN=Elastic Certificate Tool Autogenerated CA] certificate is trusted in this ssl context ([xpack .security.http.ssl (with trust configuration: StoreTrustConfig{path=certs/elastic-certificates.p12, password=<non-empty>, type=PKCS12, algorithm=PKIX})])

Can you share the relevant configuration from `elasticsearch.yml` file? My guess is that you have

```auto
xpack.security.transport.ssl.verification_mode: full

```

while it should be

```auto
xpack.security.transport.ssl.verification_mode: certificate

```
