Webhook on the RLC-520A is not being saved

Stephan

I bought an RLC-520A (Hardware Version: IPC_MS1NA45MP) and I’m experiencing the following issue. The settings for the webhook are not being saved. Regardless of whether I delete a webhook, activate it, or deactivate it, the new settings are not saved. The webhook cannot be activated using the slider. This makes the entire function useless and non-functional. As it stands, I cannot use the camera. The latest firmware is installed on the camera: v3.0.0.2839_23102301. Does anyone have a solution or the same problem?
