Drupal 8 translatable configuration - configuration

Question

I'm trying to setup a custom module that provide content from an API.The API url is configurable, but as it is different for each language I must be able to translate it. I setup my module configuration as described here (see the gist below) but when I try to access the translation form from /admin/config/regional/config-translation, i get "Access denied"
What am I doing wrong ?

First of all,
Does your custom permission configure crtib configurator is defined in a permissions.yml file ? And did you give this permission to your user ?
Where is your config/install settings file ? In your case your crtib_configurator.settings.yml ? Did you miss it ?
These files are not mandatory by default in Drupal 8, but are required once we want to make your configuration translatable.
I would suggest you this 2 articles:
Drupal 8 - How to translate the Config API
Drupal 8 multilingual tidbits 16: configuration translation development
Update - With Review of Google Drive Files
config folder should be placed in the root of your module not in src;
crtib_configurator.links.task.yml use a wrong route_name crtib_configurator.api_settings_translate, it should be crtib_configurator.api_settings.
Apply those 2 changes & clear your cache, you will then be able to use the translations form properly.
I think the main & initial error was the config folder location.
