Re: FTP TCP3D2C Connection protection error, return code -23

John,

That means your system doesn't trust the "certificate authority" that
signed the SSL certificate.

I don't believe there's a way to ignore that on IBM's FTP client, but
importing the CA(s) is fairly simple. Just retrieve the Certificate (or
CAs if you know how) and import them into your *SYSTEM store.

Retrieve the SSL certificate -

Exporting the CAs (skip the part about getting it from a website) -

Importing into your *SYSTEM store -
https://docs.bvstools.com/home/ssl-documentation/importing-a-certificate-authority-ca


I'm happy to hepl with parts 1 and 2 if you want as well. Just shoot me an
email with the address of the FTP server. If it's available to the world
should be able to get it for you.

One issue, since you're on V7R1, is that the ciphers used in the SSL
certificate may not be supported by your OS level. Hopefully you have an
OS upgrade in the works.
