Veeery slow feedback via Google Home App

Hello everyone!

Ladies and gentlemen, I need some help:

I have HA Core running under WSL. I have a Google Home app, to which I have connected a Nabu Casa account.

When I try, for example, to switch a light bulb from Google Home, the feedback from the device works as follows:

After pressing for a second, the state switches, then returns back. For example, if the light bulb was on, the state changes to “Off”, then immediately back to “On”, physically the light bulb actually switches its state, but the feedback in Google Home arrives after 20 seconds)

Could the problem be that I am using HA Core under WSL and should I expect changes if I install Green Hub?

Maybe someone has already encountered such a problem?

Well, if I were a betting man…

I’m seeing the same the last few days, between 8-15 seconds for a command from Google Home (both voice via Mini and using app). No known changes to my configuration, except for recent HA Update.

Configuration: Latest HA running on HAOS, using cloudflare tunnel, local fulfillment enabled.

In the project logs in google console, I see the following after requesting a light to turn on

(ERROR Log level)

executionType: "PARTNER_LOCAL"
latencyMsec: "6000"
isSuccess: false
statusType: "RESPONSE_TIMEOUT
fallbackToCloud: true
externalDebugString: "No message was received before the deadline."

and then another entry (DEBUG log level)

executionType: "PARTNER_CLOUD"
latencyMsec: "1303"

So for me, it looks to be something with local fulfillment taking 6s before timing out, then 1.3s for the cloud request to complete.
Do you have any logs showing similar? (https://console.cloud.google.com/logs/)
