Homematic IP Devices Not Appearing in HA

Hi everyone, I’m facing an issue with my Homematic IP devices not appearing in Home Assistant. I’ve set up HA on a Raspberry Pi 4 and integrated my CCU3 for Homematic IP. Initially, all devices were recognized, but when I added new devices, they didn’t show up in HA. I’ve tried manually adding them through the ‘Add Devices’ option, but it didn’t work. I’m also noticing some error messages about missing PING responses to the Homematic subsystem. Has anyone encountered this issue before? I’m wondering if I should reinstall the Homematic IP app or if there’s a different approach. Any advice would be greatly appreciated. Thank you in advance for your help!
