Sha256 all rejects passwords

When using long passwords, which is a must as my password list must contain a predefined long text after each password, it rejects all of them, yet if I use combination attack with the predefined text on the right with the normal list on the left it cracks fine, so basically why is sha256 rejecting passwords of long length, like 25chars or so.


If I use the passwords that cracked from the combination just as a normal straight attack, it just rejects every single one and none cracks.
