Getting this error message in logs. Does anyone have an idea what could this be indicating?  
I have checked my token endpoint through postman, and it works.

[instance-0000000001] Authentication to realm oidc1 failed - Failed to authenticate user with OpenID Connect (Caused by ElasticsearchSecurityException[Failed to exchange code for Id Token using the Token Endpoint.]; nested: SocketTimeoutException[5,000 milliseconds timeout on connection http-outgoing-0 [ACTIVE]]

Is the error intermittent? If so, you are likely hitting a known [issue](https://github.com/elastic/elasticsearch/issues/75515)

You can get around this by adjusting `net.ipv4.tcp_retries2` as suggested in this [comment](https://github.com/elastic/elasticsearch/issues/75515#issuecomment-883258339).
