unfortunatly, same here. After the update 2026.2.1 the OTBR starts, end stops after a vew seconds.

This is not the same case, because you are in 2026.2.1 and I don't have any exceptions in the log. Maybe it is preferable to open a new issue.

[sairon]

@jmcollin78 I just ran into a similar breakage on 2.16.1 myself (not updated yet, trigger by loss of connection to RCP). Can you check OTBR logs a bit further and look for something like the following line (xxx is placeholder)?

Settings file for adapter xxx already exists at /data/thread/0_xxx.data but appears to be old, archiving

[puddly]

@kdober This is a firmware bug with your adapter. Unplug it and plug it back in.

[kdober]

@puddly . You are right. I should have read the logs with more detail, sorry!
It just happens that stopped working around the update of the add-on.
Had to re-flash the firmware and it is back now

Thanks!

I am also having issues with an SLZB-MR4U on the latest OTBR version. It appears to start correctly, but none of my Thread devices are available, and when checking the OTBR web port, the status reads as:

RCP:State
disabled
WPAN service
offline

and none of the Thread devices show an IPv6 address in HA.

Settings are below, I have tried with beta off and firewall off also, but no difference:
device: /dev/ttyS0
baudrate: "460800"
flow_control: true
otbr_log_level: notice
firewall: true
nat64: false
beta: true
network_device: 10.0.0.222:6638

@jmcollin78 I just ran into a similar breakage on 2.16.1 myself (not updated yet, trigger by loss of connection to RCP). Can you check OTBR logs a bit further and look for something like the following line (xxx is placeholder)?

Settings file for adapter xxx already exists at /data/thread/0_xxx.data but appears to be old, archiving

I uninstall OTBR and re-install 2.16.1 which is working fine. So I guess I don't have access to the logs anymore. I will try to look anyway.

EDIT: no I don't have the file anymore. Should I try the new 2.16.3 ? Does this release has any link with the issue ?

[jmcollin78]

I am also having issues with an SLZB-MR4U on the latest OTBR version. It appears to start correctly, but none of my Thread devices are available, and when checking the OTBR web port, the status reads as:

RCP:State disabled WPAN service offline

and none of the Thread devices show an IPv6 address in HA.

this is not the same case. My don't start at all. I guess you have to open your own issue.

[jmcollin78]

@jmcollin78 I just ran into a similar breakage on 2.16.1 myself (not updated yet, trigger by loss of connection to RCP). Can you check OTBR logs a bit further and look for something like the following line (xxx is placeholder)?

Settings file for adapter xxx already exists at /data/thread/0_xxx.data but appears to be old, archiving

I tried with 2.16.3 and the issue is still there. The complete log is there:

@jmcollin78 Can you run docker exec -it addon_core_openthread_border_router ls -l /data/thread/ in HA OS and post the output?

@jmcollin78 Can you run docker exec -it addon_core_openthread_border_router ls -l /data/thread/ in HA OS and post the output?

I've got no docker in ssh terminal. What means "in HA OS" ? How do I access this ? I have a ProxMox installation

[puddly]

You may need to use the Advanced SSH app (https://github.com/hassio-addons/app-ssh) if docker isn't exposed in the regular one.
