Hello @Penny,
So we can better assist you, please provide a brief description of your current setup using the template I added to your first post in this thread.
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. This will provide us with a starting point for troubleshooting.
Also, please take a look at these recommendations for submitting issue reports. The more complete the report details, the quicker we can help find a solution. Thanks!
