Issues with google assistant and Home assistant

Since a couple of weeks i have issues with controlling lights through google assistant.
When i ask google to turn of light X i get a respone: Home assistant 2.0 isnt available right now, when i try 15 minutes later it works again.

If i ask google assistant to “Sync my devices” it is working immediately.

I use duckdns and nginx proxy, is this a know issue and what can i do about it?

Hi. I have same problem like yours, but I’m not use nginx proxy only duckdns addon…
I just create new project (deleted old one) and change dusckdns to dynu dns (free) and its been working great for 3 days now…
