[SOLVED] correct dm-crypt passphrase can't unlock device on startup

I'm installing Arch and encrypting the entire system. The installation process went fine but when I start up the system and enter the passphrase after being prompted "A password is required to access the cryptroot volume: Enter passphrase for /dev/sda2:" I get "No key available with this passphrase".

I can unlock the device with "cryptsetup luksOpen ..." if I boot a live-Arch from USB.

The keymap is right. I can test it by pressing keys while the passphrase is being checked and seeing the plaintext result.

Does anybody have any idea how I can solve this? There is only one available encrypted partition so sda2 should be the label of the partition I actually want to decrypt.

EDIT:

I solved it by adding a new passphrase with

cryptsetup luksAddKey ...

No idea why it worked but I can enter my system now.
