If you're running on a web server then the web server has been putting
itself into the background, thus it doesn't have a tty, thus opening
/dev/tty will fail anyway, regardless of permissions.

It's probably trying to read a passphrase, confirm a key, or whatever.

ALWAYS use --batch when calling gpg from non-terminal programs.
