## Reason One (Primary):：

When using proxy mode, the stream is pushed through the WebSocket address   ws://{{management node IP}}/{{render node IP}}/10002   to maintain a long connection. Network disconnections (initially unable to connect) or network instability (encountering error 202 during use) can lead to error 202.

### Troubleshooting and Solutions for Network Disconnections:：

1. **Intranet Environment：**

-  Check Firewall Settings: Ensure that the firewall is turned off or properly configured to allow network traffic.

- Verify Local IP Address Configuration on Render Node: Confirm that the local IP address configured on the render node matches the actual network environment.

**Refer to the following documentation：**

- [Standalone Intranet(windows)](https://docs.paraverse.cc/doc/245/)

- [Cluster Intranet(windows)](https://docs.paraverse.cc/doc/246/)

2. **Extranet Environment：**

- Check Preferred Public IP Settings: Ensure that the preferred public IP is correctly set to the external IP address to allow normal external access.

**Refer to the following documentation：**

- [Standalone Extranet(windows)](https://docs.paraverse.cc/doc/247/)

- [Cluster Extranet(windows)](https://docs.paraverse.cc/doc/248/)

By following the troubleshooting directions and solutions above, you can systematically address and resolve network disconnection issues for both intranet and extranet environments to ensure normal system network connectivity.

###**Solution for Network Instability：**

To address network instability in private deployment scenarios, you can implement front-end proactive reconnection to maintain a stable connection. The specific steps are as follows:

1. ** Enable Application Reconnection in Management Console：**

-  In the management console settings, you can configure the application reconnection feature through the path: Application Management >> Edit >> General Advanced Settings. As shown in the figure below: select the delay stream delay close, default is 20s.。

2. **Modify Configuration File   Larkxr-center\application.properties  :**

- Adjust the parameters in the file to extend the task heartbeat duration to prevent tasks from being released when the server disconnects. Restart the Admin service after making changes.

```yaml
# Default 12000 milliseconds to take a node offline without a heartbeat
# When setting task delay close, this can be changed to the duration configured in the backend, for example, 120000 (2 minutes)
pxy.clear-job.server-no-heartbeat-duration=120000
# Default 20000 milliseconds to close TaskInfo without a heartbeat
# When setting task delay close, this can be changed to the duration configured in the backend, for example, 120000 (2 minutes)
pxy.clear-job.taskinfo-no-heartbeat-duration=120000

```
2. **Web Front-End Modifications：**

## Reason Two：

The rendering package was mistakenly terminated, resulting in its absence. The complete structure of the program package is shown below:
![](https://docs.pingxingyun.com/media/202503/5731bbfcce334f07a0d53ab33e50f3884775.png)

- **Solution：**

Re-download the program package and replace the contents of the RenderServer directory.

## Reason Three：

When using a GeForce graphics card, the number of hardware encoding channels is limited by Nvidia itself. Connecting to remote tools like Sunflower will also occupy one encoding channel.

- **Solution：**

- Consider using Quadro or Tesla graphics cards, or opt for the provided all-in-one hardware and software solution to increase the number of encoding channels.

- Quadro and Tesla graphics cards typically offer more hardware encoding channels, making them suitable for high-concurrency encoding needs.

- Consider using an all-in-one hardware and software solution for more efficient encoding performance and additional concurrent channels.
