Trying to connect to CompactLogix

I'm trying to connect Node-RED to a CompactLogix PLC. I've tried using both node-red-contrib-cip-ethernet-ip and node-red-contrib-pccc, but I always get a "timeout" error. I also tried connecting using Python and encountered the same issue. However, when I connect with DeviceWise, it works fine. Could someone help me connect using Node-RED? I followed the documentation exactly.
