Here is a Kotlin version of the answer from Robert, which fixed the problem in my case:

import java.net.InetAddress
import java.net.Socket
import javax.net.ssl.SSLSocket
import javax.net.ssl.SSLSocketFactory

class MySSLSocketFactory(socket_factory :SSLSocketFactory):
      SSLSocketFactory()
{
    val sslSocketFactory :SSLSocketFactory

    init
    {
        this.sslSocketFactory = socket_factory
    }

    override fun getDefaultCipherSuites(): Array
    {
        return this.sslSocketFactory.getDefaultCipherSuites()
    }

    override fun createSocket(socket: Socket?, host: String?, port: Int, autoclose: Boolean): Socket
    {
        val socket: SSLSocket = this.sslSocketFactory.createSocket(socket, host, port, autoclose) as SSLSocket
        socket.setEnabledProtocols(arrayOf("TLSv1.2"))
        return socket
    }

    override fun createSocket(host: String?, port: Int): Socket
    {
        val socket: SSLSocket = this.sslSocketFactory.createSocket(host, port) as SSLSocket
        socket.setEnabledProtocols(arrayOf("TLSv1.2"))
        return socket
    }

    override fun createSocket(host: String?, port: Int, local_host: InetAddress?, local_port: Int): Socket {
        val socket = sslSocketFactory.createSocket(host, port, local_host, local_port) as SSLSocket
        socket.enabledProtocols = arrayOf("TLSv1.2")
        return socket
    }

    override fun createSocket(host: InetAddress?, port: Int): Socket
    {
        val socket = sslSocketFactory.createSocket(host, port) as SSLSocket
        socket.enabledProtocols = arrayOf("TLSv1.2")
        return socket
    }

    override fun createSocket(address: InetAddress?, port: Int, local_address: InetAddress?, local_port: Int): Socket
    {
        val socket = sslSocketFactory.createSocket(address, port, local_address, local_port) as SSLSocket
        socket.enabledProtocols = arrayOf("TLSv1.2")
        return socket
    }

    override fun getSupportedCipherSuites(): Array
    {
        return this.sslSocketFactory.getSupportedCipherSuites()
    }
}
