Hi @zz2, thanks for posting.
An Internal Server Error indicates that the script or page could not be processed or displayed by the server. This generally indicates and issue with the website files.
You may want to ensure that your files are compatible with the selected asp.net version.
You might also want to test your account using a simple html or txt file, to ensure that they are accessible.
If you continue to have trouble, you might want to call support to have them review/test your account.
