'You have specified an invalid directory' in field 'Default h5p package path'

Hi there, hope you can help me... I tried to integrate h5p into a fresh dupal-8.9.3 installation on a webserver. Unfortunately there is a failure when try to save the H5P-Settings because the Default h5p package path is not valid. There is only 'h5p' inserted into the field. It is such an directory inside the subfolder and the path which is show below the field is correct. Is there a solution for that issue?
