Chain validation failed - kotlin

Question

I'm having the below Okhttp code:
val client = OkHttpClient()
val mediaType = MediaType.parse("application/x-www-form-urlencoded")
val body = RequestBody.create(mediaType, "tenant_id=xxxx&client_id=xxxx&client_secret=xxxx&resource=xxxx&grant_type=client_credentials")
val request = Request.Builder()
.url("https://sxxx.com/axxx/oauth2/token")
.post(body)
.addHeader("Content-Type", "application/x-www-form-urlencoded")
.build()
val response = client.newCall(request).execute()
And want to convert it usint ktor, so I wrote the below:
class Greeting {
private val httpClient = HttpClient {
}
#Throws(Exception::class)
suspend fun greeting(): String {
val response = httpClient.request {
method = HttpMethod.Post
url {
protocol = URLProtocol.HTTPS
host = "sxxx.com"
path("axxx/oauth2/token")
// encodedParameters
trailingQuery = true
parameters.append("tenant_id", "xxxx")
parameters.append("client_id", "xxxx")
parameters.append("client_secret", "xxxx")
parameters.append("resource", "xxxx")
parameters.append("grant_type", "client_credentials")
}
headers {
append(HttpHeaders.ContentType, "application/x-www-form-urlencoded")
}
}
return response.bodyAsText()
}
}
And calling my new code as:
class MainActivity : ComponentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
MyApplicationTheme {
Surface(
modifier = Modifier.fillMaxSize(),
color = MaterialTheme.colors.background
) {
val scope = rememberCoroutineScope()
var text by remember {
mutableStateOf("Loading")
}
LaunchedEffect(true){
scope.launch {
text = try {
Greeting().greeting()
} catch (e: Exception) {
e.localizedMessage ?: "error"
}
}
}
Greeting(text)
}
}
}
}
}
#Composable
fun Greeting(text: String) {
Text(text = text)
}
But instead of getting the required token, I'm getting the response: Chain validation failed

Make sure that:
Your server certificate is valid.
Your android system datetime is correct.
