Gettig CertificateException: "No name matching localhost found" in Playframework java application

I have 2 applications, one app is in Spring Boot and other is in Playframework. I am trying to consume REST endpoint of Spring Boot application in Playframework application. I am accessing the REST endpoint using the certificate I've got. In my play application I've disabled the host name verification, but still I am getting this error. Below you can find code and configuration:

AsyncHttpClient-2-1, fatal error: 46: General SSLEngine problem
java.security.cert.CertificateException: No name matching localhost found

Spring Boot Application Configuration

application.properties

server.port=8085
server.ssl.key-alias=demo
server.ssl.key-password=changeit
server.ssl.key-store-provider=SUN
server.ssl.key-store-type=JKS
server.ssl.key-store=server.jks

Playframework Application Configuration

application.conf

play.ws.ssl.loose.acceptAnyCertificate = false
play.ws.ssl.loose.disableHostnameVerification = true

play.ws.ssl {
  trustManager = {
    stores = [
      { type = "PEM", path = "public.crt" }
    ]
  }
}

play.ws.ssl.debug = {
    all = false
    ssl = true
    certpath = true
}

If I set play.ws.ssl.loose.acceptAnyCertificate = true then it is working. I want to keep it as false and then access the end point.

I feel issue is with my configuration, that's why added config only. If more information is required, I will add the code snippets too.
