Hello Team,  
It will display **Invalid authentication token (0).** when i call following code

```auto
AmityCoreClient.setup(
            apiKey = BuildConfig.AMITY_API_KEY,
            endpoint = AmityEndpoint.SG,
        ).subscribe()

```

```auto
 private fun registerDevice(userId: String, displayName: String? = "") {
        AmityCoreClient.login(userId, object : SessionHandler {
            override fun sessionWillRenewAccessToken(renewal: AccessTokenRenewal) {
                renewal.renew()

            }
        })
            .apply {
                if (!displayName.isNullOrEmpty()) {
                    displayName(displayName)
                }
            }
            .build()
            .submit()
            .subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .doOnComplete {
                registerForPushNotifications()
                val intent = Intent(this, AmitySettingActivity::class.java)
                startActivity(intent)
            }
            .doOnError {
                findViewById<View>(android.R.id.content).showSnackBar("Could not register user " + it.message)
            }
            .untilLifecycleEnd(this)
            .subscribe()
    }

Hi @ups1995 ,

May I know if you’re using our OpenSource Android UIKit?

Thank you,
