Google Assistant Error after upgrading

I’m on version 0.91.1
I’m using DynDNS for my DDNS service.
I’m using Lets Encrypt for my cert. (cert valid until May)
I have a reverse proxy server (nginx) forwarding incoming traffic to my HASS server

Successful commands on my google home:
Me - Ok Google, sync devices.
Response - You got it, syncing devices for “the name of my google actions” and Nest.

Not Successful commands on my google home:
Me - Ok Google, turn on the family room lights.
Response - Sorry, there was an error for the family room lights.

I can turn on/off the family room lights from HASS web ui.

Here is my reverse proxy (nginx) config snippet:

server {
        # Update this line to be your domain
        server_name ha.<myDDNS domain>;
        # These shouldn't need to be changed
        listen [::]:80 default_server ipv6only=off;
        return 301 https://$host$request_uri;
    }

    server {
        # Update this line to be your domain
        server_name ha.<myDDNS domain>;
        # Ensure these lines point to your SSL certificate and key
        ssl_certificate /etc/letsencrypt/live/ha.<myDDNS domain>/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/ha.<myDDNS domain>/privkey.pem;
        # Ensure this line points to your dhparams file
        # ssl_dhparam /etc/nginx/ssl/dhparams.pem;

        # These shouldn't need to be changed
        listen 443 ssl ipv6only=off http2; # if your nginx version is >= 1.9.5 you can also add the "http2" flag here
        add_header Strict-Transport-Security "max-age=31536000; includeSubdomains";
        ssl on;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_ciphers "EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH:!aNULL:!eNULL:!EXPORT:!DES:!MD5:!PSK:!RC4";
        ssl_prefer_server_ciphers on;
        ssl_session_cache shared:SSL:10m;

        proxy_buffering off;

        location / {
            proxy_pass http://<IP of HASS>:8123;
            proxy_set_header Host $host;
            proxy_redirect http:// https://;
            proxy_http_version 1.1;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection $connection_upgrade;
        }
    }

Here is some of my HASS Google Assistant snippet:

google_assistant:
  project_id: !secret google_assistant_project_id
  api_key: !secret google_assistant_api_key
  exposed_domains:
    - switch
    - light
    - group
  entity_config:
  ###INCLUDE: 
    light.family_room_lights:
      name: Family Room Lights # Google - Family Room Group
      expose: true
    light.upstairs_lights:
      name: Upstairs Lights # Google - Upstairs Group
      expose: true
    light.living_room_lights:
      name: Living Room Lights # Google - Living Room Group
      expose: true
    light.foyer_light:
      name: Foyer Light
      expose: true
    light.downstairs_lights: # Google - Downstairs Group
      name: Downstairs Lights
      expose: true
    light.common_lights: # Google - No Group
      name: Common Lights
      expose: true
    light.dining_room_light: # Google - Dining Room Group
      name: Dining Room Light
      expose: true
    switch.chandelier:
      name: Chandelier
      expose: true

Here is the “home-assistant.log” log entry when I perform the following command:
Me - Ok Google, turn on the family room lights.
Response - Sorry, there was an error for the family room lights.

Still having the same issues…

I don’t know what I did, but it’s working now.

Darn I wish you knew what you did because I’ve tried everything. Relinking hass.io, readding all my devices, everything. Each time I always end back to this point -

Asking google assistant to do something responds with - Sorry there was an error with _____

Hassio logs are filled with the following:
Error handling message {'inputs': [{'context': {'locale_language': 'en'}, 'intent': 'action.devices.EXECUTE', 'payload': {'commands': [{'devices': [{'id': 'light.dining_dimmer_level'}], 'execution': [{'command': 'action.devices.commands.OnOff', 'params': {'on': True}}]}]}}], 'requestId': '7542447427074625062'}: {'errorCode': 'unknownError'}

I spent about a 5 hour session just straight troubleshooting everything. I redid the Google Actions and API numerous times. Around the end, I remember after resetting everything up, I unlinked and relinked my Google project from my assistant and it started working.

Did you get it up and working? If not, post up some of your configuration and let’s see if I can spot anything.
