I already logged into the system. But It didn't work!
I have run and logged in the Identity server and API. So, then I opend the browser and log in with angular, I have got the below issue. Although the Identity Server and API worked well.
:44364/api/abp/application-configuration:1 Failed to load resource: the server responded with a status of 500 () Access to XMLHttpRequest at 'https://localhost:44364/api/abp/application-configuration' from origin 'http://localhost:4200' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
