POST fails with Retrofit (connect timed out) but works with Postman [on hold]

SOLVED: stupid mistake, I had https://foo.foo.com:433 instead of https://foo.foo.com:443...

I've implemented Retrofit and I'm trying to send a POST request with JSON data as JsonObject. It's not working and I get a failure "connect time out", but I can send a POST request without problem via Postman. At first I thought it was because of the header, I've tried with an Interceptor and to use @Header instead of @Headers. Thank you for your help.

Api Interface

interface ApiEndpoints {
@POST("/")
@Headers("Content-Type: application/json")
fun sendRequest(@Body json: PostModel): Call<ResponseModel>
}


Retrofit Client

class ApiClient {
val service = Retrofit.Builder()
.baseUrl("https://foo.foo.com:433")
.client(client) // Implement HttpLoggingInterceptor()
.addConverterFactory(GsonConverterFactory.create())
.build()
.create(ApiEndpoints::class.java)
}


Api Call

val test = ApiClient().service.sendRequest(
PostModel("web",
"ggrojeomieje2",
105,
"signal",
1,
"signal",
Params())
)

test.enqueue(object : Callback<ResponseModel> {
override fun onResponse(call: Call<ResponseModel>?, response: Response<ResponseModel>?) {
println("response " + response?.body()?.params?.timestamp.toString())
}

override fun onFailure(call: Call<ResponseModel>?, t: Throwable?) {
println("failure " + t?.message.toString())
}
})


Models

data class ResponseModel(val params: Params?)


data class PostModel(var transport: String? = null,
var userId: String? = null,
var moduleId: Int? = 0,
var moduleName: String? = null,
var moduleVersion: Int? = 0,
var operation: String? = null,
var params: Params?
)

data class Params(var timestamp: Unit? = null)


Response

{"params":{"timestamp":1.530346984546E9}}

Try to set time out value in OkHttpClient.

OkHttpClient

val client = OkHttpClient.Builder()
.connectTimeout(30, TimeUnit.SECONDS)
.writeTimeout(30, TimeUnit.SECONDS)
.readTimeout(30, TimeUnit.SECONDS)
.build()


Also try changing request body types like x-www-form-urlencoded or form-data and header like this @Headers({"content-type: application/json"})

x-www-form-urlencoded

form-data

@Headers({"content-type: application/json"})

or

Check is there any network related issue or just try some simple GET method too failing.

GET

Failed to connect to foo.foo.com/54.246.216.106:433

https://foo.foo.com:433

https://foo.foo.com:443

Stupid mistake, I had https://foo.foo.com:433 instead of https://foo.foo.com:443...
