Homematic Integration failed on with HA on TrueNAS

Hi there,
I am operating HomeAssistant for quite a while on a raspi.
Installation contains Shelly / IKEA / other Zigbee and quite a bunch of Homematic devices.

After installing TrueNAS, I thought it was a good idea to move HA to a container which went perfectly well.

Since a couple of days I realised, that values will be not refreshed after start and commands are not possible.

On the other hand: connection somehow is possible. I added a system variable in HM and it was shown in HA.

HA is complaining “Pong Events” - any Idea, what this is meaning?

Have you configured a bridge on your TrueNAS?

I don’t know if it will help, but I’ve seen various communication issues solved by using a bridge.

Yeah, obviously somme communication problems, as login HA <=> HM and transfer of variables works.
Tried different port-options, but nothing worked.

Finally I decided to set up HA in a virtual machine this morning and it was quite easy. Uploaded backup from my Raspi and it works great.
