### **5. Cannot access to the Web App**

<mark style="color:red;">**Reason**</mark><mark style="color:red;">:</mark> the Mainboard Ethernet IP is not correct&#x20;

&#x20;<mark style="color:green;">**Solution**</mark><mark style="color:green;">:</mark> Get the IP in the bottom left corner of video streaming

<figure><img src="https://3309772875-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FnikHUDUd2JXqkOsnOi7l%2Fuploads%2FHHBcrAOUbvGmdlhUHVpB%2Fimage.png?alt=media&#x26;token=df90ceaa-1fad-4cb8-a3b0-070355a0c467" alt=""><figcaption></figcaption></figure>

### **6. Cannot open the Camera Menu Setting on QGC**

<mark style="color:red;">**Reason**</mark><mark style="color:red;">:</mark> the first time the QGC app connects to the drone system, including the Mainboard, the remote needs internet access to download the Camera Menu Settings

<mark style="color:green;">**Solution**</mark><mark style="color:green;">:</mark> close the QGC app, connect the remote to the internet, and then reopen the QGC app.

### 7. Unable to Stream IR

One possible reason is that the protective film or sticker on the connection port between the camera and the gimbal has not been removed. This may block the signal and prevent the IR view from functioning properly.

Please check and ensure that any protective film has been removed and that the connection is clean and secure.
