Harmony Hub and IKEA Trådfri not working to 2.4

The Trafri issue is known for a long time, but neither the cause nor a solution are known so far:

I created a bug report, as I am unfortunately no Java programmer:

The issue described here https://github.com/eclipse/smarthome/pull/6193 was disc…ussed and a solution proposed. Still, it does not work reliably. There is a discussion in the OpenHAB forums here: https://community.openhab.org/t/tradfri-binding-loses-connection-after-power-failure-gateway-reboot/47833/61 ## Expected Behavior When the OpenHAB server boots, it should establish a contact to the Tradfri gateway. This connection should be stable. ## Current Behavior The connection is not reliably established after boot. One has to re-enter the credentials to get the binding online again. ## Possible Solution Try to re-establish the connection if it gets lost (and keep the credentials) ## Steps to Reproduce (for bugs) 1. Install the Tradfri binding 2. Enter credentials. Gateway comes online. 3. Wait. Reboot. Gateway does not come online at 2 out of 10 reboots. 4. Enter credentials again. Gateway comes online ## Context I run a Tradfri gateway to switch some bulbs. ## Your Environment * Version used: OpenHAB, milestone, currently 2.4 release * Raspberry Pi 3B+, running OpenHABian
