Hello after a year since i last updated it, i tried to log into my project as every days. But it’s not working anymore, i tried to upgrade to the last version of the gem for rails, but it’s still not working..

I get `net::ERR_CONNECTION_CLOSED` in the console as you will see into the below screenshots

## Context

**My CORS config :**

```javascript

    config.middleware.insert_before 0, Rack::Cors do
      allow do
        hostnames = [null_regex, 'localhost:4200', 'app.forestadmin.com', 'localhost:3001']
        hostnames += ENV['CORS_ORIGINS'].split(',') if ENV['CORS_ORIGINS']

        origins hostnames
        resource '*',
                 headers: :any,
                 methods: %i[get post options delete put],
                 max_age: 0,
                 expose: ['Content-Disposition'],
                 credentials: true
      end
    end

```

**Forest\_liana.rb** the 3 are called on the os level for sure

```javascript
ForestLiana.env_secret = Rails.application.secrets.forest_env_secret
ForestLiana.auth_secret = Rails.application.secrets.forest_auth_secret
ForestLiana.application_url = Rails.application.secrets.forest_application_url

```

**Forest rails gem version =\> 6.0.3**

I you need more informations, feel free to ask.

Thanks for you help

Hey @Joe_Marc,

We recently had a few instabilities on the platform. May I ask you to try again now, and tell me if you are experiencing any issue?  
Also, did you follow the upgrade to v6 note available [here](https://docs.forestadmin.com/documentation/how-tos/maintain/upgrade-notes-rails/upgrade-to-v6)?

If possible, could you also share your project name?

Thanks in advance 🙏

Hello @Joe_Marc,

I think there is an extra point at the end of the remote address you configured for your remote environment. Forest Admin is trying to contact `https://api-staging.waiter.fr./forest/authentication` which does not look like a valid URL.

Can you change the configuration of this remote environment and fix the URL?

I made the change directly in our system, the extra dot was still present.

Can you refresh your browser and test again?

Thanks for the update, i have the same error but without the dot now !  
`https://api-staging.waiter.fr/forest/authentification`

I don’t really understand it since i don’t manage the endpoints `/forest`

My backend works fine at `https://api-staging.waiter.fr`

Ok, thanks for sharing this error.

It seems that there is an error with the secret named `forest_application_url`. Can you check that its value is correctly configured with `https://api-staging.waiter.fr` in yout `secrets.yml`?

Hello,

Yes the value is configured in the vars of heroku as i always do.

The error you received indicates that this value was not correctly loaded by the application. Can you check that your application correctly receives this value, and uses it?

In the file `config/initializers/forest_liana.rb` you should have these 3 lines:

```javascript
ForestLiana.env_secret = Rails.application.secrets.forest_env_secret
ForestLiana.auth_secret = Rails.application.secrets.forest_auth_secret
ForestLiana.application_url = Rails.application.secrets.forest_application_url

```

Do you have a way to log the value that is set to `ForestLiana.application_url`? I’d like to be sure that the value is correct, because the error that is returned by the server clearly indicates that the string received is `\"\"`

I just logged it from heroku and i get the value.  
Yes in the network response of the server the value is empty … i don’t understand why

```javascript
The registration to the authentication API failed, response: {\"error\":\"invalid_redirect_uri\",\"error_description\":\"Redirect uris must be an array of valid urls. Received: \\\"\\\".\"}"

ok, here you retrieved the environment variable set on heroku.

I would like to be sure that the application itself and the liana is using the right value. I would like to be sure that `ForestLiana.application_url` is really equal to this value.

In addition to that, I find it strange that the value that is logged here is not exactly the same than the one you shared before: there is an extra slash at the end.

If you use `puts`, I guess that the line should appear in logs on heroku (you can access them on the web interface, or with the CLI)
