Akka kubernetes api discovery - javax.net.ssl.SSLHandshakeException: General SSLEngine problem

During a CA rotation our service stopped working. The readiness probe failed with the following error:

 {"@timestamp":"2021-01-29T12:38:57.943Z","@version":"1","message":"Querying for pods with label selector: [app=xxx]. Namespace: [xxx].

We tried to disable the hostname verification with no luck

ssl-config {
loose {
disableHostnameVerification = true
}
}

The problem is that there are 2 certificates on the server in the ca.crt as a bundle, the old and the new one and for some reason it’s not parsing the new one . I’d appreciate if you could help with this. Thank you
