Hi Franco,

I am not sure the issue is anything to do with networking, it fully works from Unity editor and I think the error from brainCloud is potentially misleading.

I am using Unity 2021.3.8f1

After tracing it back tracing it back through, the error is being generated byBrainCloudComms.cs, specifically private void HandleResponseBundle(string jsonData), If I enable debugging and run on an iPhone, I get output of:

19:22:40.664 #BCC RESPONSE - 21/04/2023 19:22:40

false

The function then tries to decode the json:

JsonResponseBundleV2 bundleObj = DeserializeJsonBundle(jsonData);

The next bit of output is then:

19:22:40.666 #BCC Only objects with default constructors can be deserialized. (BrainCloud.Internal.JsonResponseBundleV2)
UnityEngine.DebugLogHandler:Internal_Log(LogType, LogOption, String, Object)

BrainCloud.BrainCloudClient:Log(String)
BrainCloud.Internal.BrainCloudComms:DeserializeJsonBundle(String)
BrainCloud.Internal.BrainCloudComms:HandleResponseBundle(String)
BrainCloud.Internal.BrainCloudComms:Update()
BrainCloud.BrainCloudClient:Update(eBrainCloudUpdateType)
BrainCloudWrapper:RunCallbacks()
BrainCloudWrapper:Update()

Received an invalid json format response, check your network settings.

So data is definitely making it back from the server, but then if I log in from Unity editor, the response from BrainCloud looks similar?
