Hi @Bobby_Stankov,
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.
Often times a reboot will help with this type of behavior. Can you try rebooting your Core machine and let us know if there is any change?
Thanks!
