Service Unavailable 503 issue in Sharepoint Server 2019

Hi Every one ,

I had installed SharePoint 2019 as a Single Server Mini Role in Server for testing out the new features. However, After the installation, When I tried to access Central Admin Site , I received ‘Service Unavailable’ error.

In Event Viewer I got 

"An exception occurred when trying to issue security token: The HTTP service located at http://localhost:32843/SecurityTokenServiceApplication/securitytoken.svc is unavailable. This could be because the service is too busy or because no endpoint was found listening at the specified address. Please ensure that the address is correct and try accessing the service again later.. "

I have Sharepoint farm account which is member of Local Admin and sysadmin server role in database

Please suggest me how to solve this problem?

Thanks
