Tradfi throws errors

Hello!

I just got a Mac Mini and moved my home assistant config to a new instance of home assistant to the Mac in Docker.
Everything is working nicely and finally its really fast but Tradfri integration is acting strange. I successfully integrated it and when I start/restart Home Assistant, everything is working for a while then suddenly it stops working. I have a lot of errors in the logs:

2019-11-01 08:33:00 ERROR (MainThread) [coap] Exception CancelledError() can not be represented as errno, setting -1.

I got this several times for all my Tradfri devices (remotes, switches, bulbs), and then:

I already tried to remove/readd the integration from the UI, restarted Tradfri gateway.
My configuration has these (gateway is on fixed ip):

tradfri: 
  host: 192.168.10.102

Do you guys have any idea what could be wrong? It was working fine on my rpi 3 with hassbian (I cannot remember the exact version of home assistant but it was around 0.98.*). My current version is the latest (0.101.1).

I also have Homekit and it works fine while home assistant integration is not responding.

Thanks!
