Hi @Stuart_Matheson,
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.
Can you elaborate a bit on what settings you changed?
Are you able to play okay to other endpoints?
Can you share a screenshot of device setup for the endpoint you’re trying to use?
