If problems with abrupt closing of sessions opened in the database via RemoteApp are identified, and furthermore the platform does not allow more than one user to remain logged in at the same time, the causes of these problems are alterations in the GPOs and registry keys of Windows servers, which prevent simultaneous access with the same credential on the device.
To solve these problems, make changes to the GPOs and registry keys, which allows simultaneous access of multiple users with the same credential and avoids abrupt closing of sessions opened in the database via RemoteApp.
