As a workaround, on the JVM target using CIO engine, you can accept all certificates:

val client = HttpClient(CIO) {
    engine {
        https.trustManager = object : X509TrustManager {
            override fun checkClientTrusted(certs: Array<X509Certificate?>?, authType: String?) {}
            override fun checkServerTrusted(certs: Array<X509Certificate?>?, authType: String?) {}
            override fun getAcceptedIssuers(): Array<X509Certificate?> = arrayOfNulls(0)
        }
    }
}

Also, you can add a certificate chain:

HttpClient(CIO) {
    engine {
        https.addCertificateChain(...)
    }
}
