I have increased the socket timeout to 15 minutes since I am trying to reindex ~ 40k records. But within 6 minutes I get below exception : ```auto Caused by: org.springframework.dao.DataAccessResourceFailureException: Tag mismatch!; nested exception is java.lang.RuntimeException: Tag mismatch!

The root cause is `Caused by: javax.crypto.AEADBadTagException: Tag mismatch!` which indicates an issue in the TLS/SSL layer, out of the realm of the Java client and Spring Data. Googling it shows some issues in some TLS 1.3 implementations. [Failure with javax.crypto.AEADBadTagException due to a defect in Java 8 TLSv1.3 implementation](https://www.ibm.com/support/pages/failure-javaxcryptoaeadbadtagexception-due-defect-java-8-tlsv13-implementation) You should look at the JVM version, its configuration, or maybe the SSL setup of your Elasticsearch deployment. ---
