Django rest framework does not allow connection

Question

I'm making android app with django server.

I use django rest framework

When android app send some data to server, there is no log django server showing in cmd. and server do not get any request.

But with postman, everything works well

I think there is an error at server part

This is my django settings.py

Could you tell me what part should i fix or is it android's problem

Edit

I put some android code. I use retrofit2, rxJava2 and Koin as di

this is function in my viewModel

fun verifyToken(token: String) = addDisposable(userService.verifyToken(TokenRequest(token)), getMsgObserver())

This is addDisposable function

fun addDisposable(disposable: Single<*>, observer: DisposableSingleObserver<Any>) {
        compositeDisposable.add(
            disposable.subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread()).subscribeWith(observer)
        )
}

This is all about getMsgObserver

fun getMsgObserver() = MsgDisposableSingleObserver()

inner class MsgDisposableSingleObserver : DisposableSingleObserver<Any>() {

    override fun onSuccess(t: Any) = filterMsgFromResponse(t)

    override fun onError(e: Throwable) {
        networkError.call()
}

And this is UserService interface and it's impl

interface UserService {
    fun verifyToken(tokenRequest: TokenRequest) : Single<retrofit2.Response<Response<Any>>>
}

class UserServiceImpl(private val api: UserApi) : UserService {
    override fun verifyToken(tokenRequest: TokenRequest) = api.verifyToken(tokenRequest)
}

And this is UserApi which used by UserServiceImpl

interface UserApi {
    @POST("/diary/verify/")
    fun verifyToken(@Body token: TokenRequest) : Single<retrofit2.Response<Response<Any>>>
}

when i call function verifyToken i get an error through MsgDisposableSingleObserver's onError function and Error Message is

failed to connect to /10.80.162.133 (port 1289) from /10.80.163.129 (port 60989) after 10000ms

Edit

val retrofit: Retrofit = Retrofit
    .Builder()
    .baseUrl(BASE_URL)
    .addConverterFactory(GsonConverterFactory.create())
    .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
    .build()

The BASE_URL is server url which i try to connect to
