Unable to connect to unleash server on Unity Android App

[rahul-Inspirit]

Hi team,

I'm using Unity Game Engine to develop an android app. Using this package I'm able to connect to Unleash server and fetch toggle payloads, but it works only in the Unity Editor (I'm using a Mac).

When I build and run the apk on the mobile device, I'm unable to connect to Unleash server. There are no errors in the android logcat. I'm using Serilog package for Unleash logs. I do get connection errors in the Unity Editor if there is something wrong in Unleash settings.

In the mobile device, execution hangs at this line
IUnleash unleash = await unleashFactory.CreateClientAsync(settings, synchronousInitialization: true);

I'm not able to understand the cause of this issue. Please HELP!

Hello @rahul-Inspirit!

Could you tell me a little bit more about your setup? Is Unleash hosted locally on the same network as your Mac?
How does the configuration get applied to Unleash settings, and have you configured a custom timeout setting on the UnleashSettings? By default it should time out after 5 seconds

Thanks @daveleek

Yes, the code works when running locally on my Mac in Unity (NOT Unreal) editor.
The same code doesn't work on android.

I don't have evidence that it has fetched the toggles from Unleash and written it to cache, I think it doesn't even connect to Unleash.
I tried the CreateClient method. It also runs fine in the editor but gives the following exception on android:

Hey @rahul-Inspirit, what version of Unity and Android are we working with? I'm hoping to try and replicate the behavior.

[rahul-Inspirit]

Hi @mvittiglio
Unity version - 2021.3.23f1 (Silicon)
Android version - 12

Just a heads-up, we haven't had the chance to test or officially support using Unity for Android with the .NET SDK.
