Couldn't find the camera that matches the specified Device User ID but was found by pylonviewer

Describe what you want to implement and what the issue & the steps to reproduce it are:

I have three GiGE cameras (left, middle, right) connected to a Jetson Orin AGX via a Forge Carrier Board. Using the pylon_camera_wrapper, I can only access two cameras and retrieve images (middle and right). It cannot find the camera with DeviceUserId=left. I can access all cameras through the Pylon Viewer without problems.

...

Does anyone have an idea what could be causing this?

Is your camera operational with the Basler pylon Viewer on your platform?

Yes

Hello @SebGoCCC Does your left camera have a manually set IP address? See here: https://github.com/basler/pylon-ros-camera?tab=readme-ov-file#no-connection-with-connected-camera Did you try to connect to just this one, by disconnecting from your network the 2 other cameras?

Hi Yes, all cameras have a manually assigned IP address. I disconnected the other cameras and tried again. It seems to be working now. Even when all of them are connected to the Jetson Board. Do you have any idea what might have caused the issue so that I can avoid it in the future?
