Fairly new to HA (HA Green). I setup a SLZB-06 as a ZigBee coordinator. It has been working fine and I installed over 40 ZigBee devices so far. Had it mounted with tape to a wall while getting things set up. Today I removed the tape and used command tape to stick it to the wall. Now the ZigBee network is not functioning. I get the following:

I had this error when I first set this up but a firmware update took care of the issue. I tried updating the firmware again from 2.3.6 to 2.7.1. No change. I saw a post that they whet to an older version and it started working. Changed it back. No change, same error.
The IP address is reserved and it seems to point to the correct place. I can bring up the web interface for the SLZB-06 fine. That is how I did the updates.
I did notice that the showed uptime of only a few hours which is about when I remounted the device to the wall. I did not unplug it at all so it shouldn’t of shut down. I am using POE and there is plenty of power available.
I did install a Everything Presence Lite device too today. Thought that might that had some connection to the issue so I did a restore using yesterdays backup. After over 1.5 hours and the restore window never went away. I clicked on HA page and then it went away. Seems like the backup did restore from what I can see.
Found the issue. I looked at the dashboard again directly for the SLZB-06. I noticed that it stated that it is connected via USB. Went in the settings and changed it back to Ethernet. Once I did that the system started working again.
I don’t know how it changed to USB but somehow it did.
Thank you! I just had the same issue. I have my SLZB-06 powered over POE and it was mysteriously set up for USB mode all of a sudden.
Seems that only fixed part of my issue, I had to reflash the zigbee firmware on the device because Z2M just kept timing out when connecting. Did you also have this issue?
Hi, @boltinbear BIG thanks for posting the logs (which made it easy for me to find this post) and the solution. I had the same problem where the Add-On would not start and I was struggling for 1 month+ to find a solution. Switching it from USB to Ethernet solved it right away (SLZB-06 dashboard > Mode > Connection Mode > Ethernet)
It still begs the question why it change to USB. Seems like many of us had this happen sometime in February of this year.
Can I please seek assistance as I did a Zigbee Coordinator OTA update - 20240710 and after that my Zigbee dashboard fails to load. I have the following error showing:

Hello,
I’m facing this same issue but didn’t check if the SLZB-06 switch to USB connection, I need to verify this next time if occur. My log’s looks similar

I was trying to reboot SLZB remotely but this not give the result, only hard ethernet cable disconnection does the job. I’m powering via PoE
Thanks for this. I ran into the same issue after moving the SLZB-06 to another room.
The only thing I can think of is that I powered it on using POE, but my POE adapter didnt have the lan ethernet in it the first time I powered up. So when it saw there was no network connection is reverted to USB.
