Tradfri gateway not reachable after update to 1.17.19

I just followed the app suggestion to install an update and my tradfri gateway was updated to 1.17.19.

Unfortunately, my tradfri binding 3.1 cannot communicate with the gateway any longer:

2021-12-21 08:12:25.588 [INFO ] [ab.event.ThingStatusInfoChangedEvent] - Thing 'tradfri:gateway:gwa0c910675aa5' changed from OFFLINE (COMMUNICATION_ERROR) to UNKNOWN
2021-12-21 08:12:25.593 [INFO ] [ab.event.ThingStatusInfoChangedEvent] - Thing 'tradfri:gateway:gwa0c910675aa5' changed from UNKNOWN to OFFLINE (COMMUNICATION_ERROR)

Am I the only one? If not, any idea how to debug or fix this?

Hello Patrick,
my GW is still alive an online. At least my logs are telling me that.
OH2 2.5.12

unfortunately i have other problems. Sending commands from OH2 to GW is not working.
I can receive but can not send :frowning:
see this thread

Fixed after updating to OH 3.2.

Hi , is this broken again with FW 1.17.44?
I can see status changes but can’t control Tradfri items with OH 3.3.0.M3 and OH 3.3.0.M4.

Edit: I did remove items (blinds) and bridge, removed binding, re-added them. No change, I can’t send commands to these items. and don’t see any error messages.
