I've checked it and it works just fine. I'm able to encrypt to it
without any problems.
I'm afraid that doesn't leave you with a good answer, though. I don't
think it will help, but it's worth trying making a larger key, as I
suggest above. Aside from that, your bank or whoever you are
communicating with needs to give you some more information about why
this is failing.
