Unable to open password protected PDF (256 bit encryption)

[NI3]

The user is unable to open Password protected PDF(Open and/or Edit password) with 256-bit encryption even if the correct password is entered.

When I tried accessing both password protected .pdf files i.e with edit and password to open, it asks for the password.
After entering the correct password it still keeps asking for password and file doesn't open.

Hi Maxim,

I tried to open the same document on the latest release of Document Server but still facing the same problem. The issue persists even in the latest build of Documents Server?
