Hi have you read about CORS in all ADF documents or previous questions?

https://github.com/Alfresco/alfresco-ng2-components/blob/development/ALFRESCOCORS.md

https://github.com/Alfresco/alfresco-ng2-components/blob/development/PREREQUISITES.md

For more information about CORS please crawl in internet also is a really common problem between Front End and Back end app when they are not on the same domain

Thanks for your help. My issue is solved by enabling CORS in activiti app properties file and setting correct provider property in app.config.json.

For our project we use only BPM service, So I set providers property as "BPM".
