Ikea Tradfri stops working within 24h

[nskn71]

Home Assistant release with the issue:

Last working Home Assistant release (if known):
either 0.76.2 or 0.84.2, not sure exactly. It was working well until a release during the winter.

Operating environment (Hass.io/Docker/Windows/etc.):

0.84.2

arch	x86_64
dev	false
docker	false
hassio	false
os_name	Linux
python_version	3.6.5
timezone	Europe/Stockholm
version	0.89.1
virtualenv	true

Fixed IP addresses both for Trådfri GW and Home assistant, both HA and Tradfri are hardwired (no wifi).

Description of problem:
After a period of time, ususally within 24h, Home Assistant looses connectivity with the Ikea trådfri gateway and lights/sockets become unavailable and can not be controlled. The Ikea Trådfri app works without issues, only HA have this problem. Power cycle on Trådfri GW does not resolve issue, I need to restart HA in order to restore connectivity.

Additional information:

Issue seem to have started around 17:38:03.

I've seen other in the forums so I'm not the only one with this problem.
Let me know if any more information is needed.

[TychoWerner]

I've had the same issue, just now removed the gateway from Home Assistant and readded it. Let's see.

[timdonovanuk]

I just had the same issue. I'm on 0.88.0. I couldn't grab the log because I had to quickly reboot HA to restore service, but I did quickly manage to see ERROR (MainThread) [coap] Exception CancelledError(). Usually issues with Tradfri I just unplug the Tradfri gateway and that restores control, but on recent versions of HA I have to also reboot HA.

[bouwew]

I have the same problem several times per week!

I'm running the Circadian custom components, so lots of communication to my 13 various types of Tradfri bulbs.

Have same issue, and have for awhile. I see no errors in this regard. it works ok after hass reboot, then goes slower and slower, until it doesn update states. Tradfri app works as intended, so it is definitely not the gateway. Sorry, not very useful info, as I see no errors.
