Hi everyone,

I’m in the process of migrating to a new Auth0 custom domain.

Previously, with the deactivated domain, I was seeing a **“wrong redirect uri”** error. I updated the redirect URI in both **Google** and **Apple** developer consoles to match the new custom domain:

```auto
https://new-custom-domain-name/login/callback

```

Now, instead of the wrong redirect URI message, I’m getting this error during Google login:

```auto
{
  "error": "access_denied",
  "error_description": "missing_host"
}

```

And here’s the corresponding Auth0 log entry:

```auto
{
  "date": "2025-10-15T18:55:05.008Z",
  "type": "f",
  "description": "missing_host",
  "connection": "google-oauth2",
  "connection_id": "",
  "client_id": "my-client-id",
  "client_name": "my-client-name",
  "ip": "159.48.52.103",
  "user_agent": "Chrome 141.0.0 / Mac OS X 10.15.7",
  "details": {
    "body": {},
    "qs": {
      "state": " ****************************"
    },
    "connection": "google-oauth2",
    "error": {
      "message": "missing_host",
      "oauthError": "access_denied",
      "type": "oauth-authorization"
    },
    "session_id": "id",
    "actions": {
      "executions": [
        ""
      ]
    },
    "stats": {
      "loginsCount": 9
    }
  },
  "hostname": "new-custom-domain-name",
  "user_id": "google-oauth2|userID",
  "user_name": "USER@gmail.com",
  "strategy": "google-oauth2",
  "strategy_type": "social",
  "audience": "Audience",
  "scope": [
    "openid",
    "profile",
    "email",
    "offline_access",
    "read:current_user",
    "update:current_user_metadata"
  ],
  "$event_schema": {
    "version": "1.0.0"
  },
  "environment_name": "prod-us-4",
  "log_id": "id",
  "tenant_name": "dev-tenant",
  "_id": "id",
  "isMobile": false,
  "location_info": {},
  "id": "id"
}

```

Everything else (client\_id, audience, scopes, DNS, etc.) seems correctly configured, and the domain resolves fine. This only started happening right after updating to the new custom domain and updating redirect URIs in the Google/Apple console.

Has anyone encountered the **`missing_host`** error after switching a social connection to a new custom domain? Is there an additional step required on Auth0 or social provider side after changing the domain?

Any guidance or hints on what I might have overlooked would be appreciated!

Hi @gedeon.u

Could you please let me know if you are using any kind of reverse proxy for your custom domain?

Also, is the **Origin Domain Name** assigned to your custom domain the one used for the **host** header?

Kind Regards,  
Nik
