SLZB Zigbee Adapter keeps losing connection to OpenHAB

Hello everyone,
I’m having trouble with my SLZB Zigbee adapter and I’m hoping you can help me. The adapter keeps losing connection to OpenHAB, and I’ve already tried a few troubleshooting steps.
Here’s what I’ve tried so far:

  • Installed the latest firmware for the SLZB Zigbee adapter
  • Restarted the adapter and OpenHAB several times
  • Connected the adapter to different USB ports
  • Tested connection via USB, Wi-Fi, and Ethernet
  • Checked OpenHAB logs (“Connection refused” error)
  • Verified IP address and port in OpenHAB configuration
  • OpenHAB is running in Docker in host mode
  • Pinged the adapter from the Docker bash (successful)
  • Device type in OpenHAB configuration is detected automatically

Does anyone have an idea what could be causing this? I’m grateful for any advice!
Thanks in advance!

Could you post the error that you see in the logs please. Are there errors on the docker host as well as OH?

I’ll work on that in the coming days (once it cools down) and will be in touch again. Thanks for your patience

Could it be related to that? Is there a suitable firmware for the dongle?
