The remote end may not support the more secure ciphers.  If they are running an older FTP server that still uses SSL, you may have that disabled on your system being that you are already at 7.1  Look at the system values QSSLCLS, QSSLCLSCTL, and QSSLPCL.
Mine are set at:

What version of the OS are you running?  The new remote FTP server may allow only more secure TLS with stronger ciphers.  Depending on your OS there may be PTF's to add the newer SSL and stronger ciphers.

Subject: FTPS Error
Greetings,
I am getting the following error
No ciphers available or specified.
When I try the FTP command on the i, using SECCNN(*SSL) option.
Of note, I am able to FTP using SSL to three different locations without a problem. This new connection is for another client that is now doing secure FTP. I have installed the CA in the System Store using DCM.
Any ideas on how I can get past this error?
