sslv3 alert handshake failure

I am receiving an SSL handshake failure error. I have an RDS MySQL instance running with CA rds-ca-ecc384-g1. In DMS I created an endpoint to this RDS instance. When checking the endpoint connection I am receiving this error. If RDS CA is rds-ca-2019 I am not facing this issue but that CA is gonna expire next year. I tried with certificate bundles from this https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/UsingWithRDS.SSL.html#UsingWithRDS.SSL.RegionCertificates but still facing the issue. Unable to find any guide or question related to this online. Did anybody face this issue?
