Hi @Pierre-Yves_Touche -
The service won’t be accessible through a browser if it does not start successfully, which is what is happening here.
The “existingClientAppIds failure: An error occurred authenticating: invalid username/password” error seen in your logs can happen if the metadata database contains a previous installation of Charts, but the mongodb-charts_keys volume does not contain the required credentials. If you’re attempting a fresh installation, the easiest thing is to delete all data in the database and remove the Docker volume and start again.
