Code was working before upgrading to CMS v3.1.3. Media was being uploaded with a tag via the api. Now we get this exception:
Type: Xibo\OAuth2\Client\Exception\XiboApiException
Message: {“error”:“invalid_client”,“error_description”:“Client authentication failed”,“message”:“Client authentication failed”}
Filename: /var/www/html/xibo_submission/Xibo/Provider/Xibo.php
Saw one similar issue (3.0 API authentication issue) when upgrading to 3.0 and he mentioned something about the redirectionUri on the application settings page and when creating provider object but the solution was vague and not sure if related to my issue or what it should actually be set to.
