Live View Fails for WebRTC and MSE ("404 Not Found") After Updating to v0.44.0 #670

After updating LightNVR to version v0.44.0, the Live View feature fails to render camera streams when using either WebRTC or MSE streaming modes.

Expected Behavior
Live View should successfully connect to the go2rtc service via WebRTC or MSE and render the camera streams smoothly without routing errors.
