Hello @Felix_P, and my apologies for the delayed response here. Do you have another device we can use as the core temporarily so we can narrow this down to the possible source of the issue? Thanks! I’d also like to know more about your network setup, would you kindly fill out the template below?
So we can better assist you, please provide a brief description of your current setup using this link as a guide.
Make sure to describe your network configuration/topology, including any networking hardware currently in use, so we can have a clear understanding of how your devices are communicating.
