Hello there,
I have been working with a Digi ConnectPort X4 to connect a network of remote devices via ZigBee; but I have encountered some persistent issues with maintaining a reliable connection. I am hoping someone here might have insights or suggestions to help resolve these problems.
The issue I am facing is inconsistent connectivity between the ConnectPort X4 and the remote devices. Sometimes the devices connect seamlessly; but at other times; they fail to establish or maintain a connection; resulting in dropped data and communication failures.
I have tried adjusting the network parameters; resetting the devices, and even relocating the X4 to reduce interference; but the problem persists.
I have also monitored the signal strength and network diagnostics via Digis configuration tools; but everything seems normal when the devices are connected. Although, the issue reappears unpredictably; making it hard to troubleshoot.
Also, I have gone through this post: https://forums.digi.com/t/how-to-connect-the-gateway-connectport-x2-to-digi-device-cloud-minitab which definitely helped me out a lot.
Has anyone else experienced similar issues with the ConnectPort X4? Are there any specific configurations or troubleshooting steps I might have overlooked? 
Thank you in advance for your help and assistance.
