To me this sounds like you made some mistake at entering the passphrase.
This is a plain dm-crypt device, so cryptsetup is unable to check for
correct password. Only proof is a valid filesystem on the unlocked
dm-crypt device.

Please provide further information in case that you still suffer from
this issue.

Kind regards,
