I tried built a client following the steps below, but it crashes when I start the application on Oculus Quest 2.  
Can someone please guide me on what could be wrong here ?

[https://docs.nvidia.com/cloudxr-sdk/unity\_guide/guide.html](https://docs.nvidia.com/cloudxr-sdk/unity_guide/guide.html)

Unity version: 2022.2.12f1  
Oculus Quest 2 Version: 59.0.0.172.706.535797236  
CloudXR Server: 4.0.0  
UnityPlugin: 0.1.0

Here are the Client and Server logs.

On client device(Quest 2), you can find extra log file, it must be on path of [Application.persistentDataPath](https://docs.unity3d.com/ScriptReference/Application-persistentDataPath.html). You will find two important log file. I recommend delete all files and try to start you app again. There will two important log file CxruAutoconnectSampleLog\_\*\*\*\*\*.txt and Streamer\_Client\_Log\_\*\*\*\*.txt. If there are any problem, you will find it there.

Thank you for your reply.

When I checked the log, I found the following error.

```auto

```

So I tried the following but could not connect.

- Disable the server firewall
- Check the security group settings for the server instance

Do I need to make any settings on the client device (Quest2)?

Was self resolved. The router settings were not correct.

After check the settings, I was able to connect.

Thank you for watching.
