America First Credit Union

I get an "account not found error" trying to connect to AFCU.

I run this command in Terminal:

openssl s_client -connect ofx.americafirst.com:443

Then I paste the following:

And I get this response:

So apparently, the sign in works, but for the BANKMSGSRSV1 I get a error code 2003, which I understand means "account not found". Any ideas what the problem is?
