Log Details (Warning)

I’m showing this warning this morning. Googling it shows a possible attack? I use Nabu Casa. Don’t use port forwarding or a VPN. Should I be concerned about this?

Thanks for any pointers.

I am getting same warning. Are you using any Tuya integrations? Not sure if they are related but i recently installed them and getting bunch of other errors/warnings with local tuya/ tuya mentioned in them.

Exactly the same thing. First time seeing this.
I have always used Tuya integration.

No Tuya integrations. I do have several Salus SP600 Zigbee switches though.
