We had to manually download and add the intermediate certificate.
This is crazy... these certificates expire every 90 days. Surely they should renew.

Subject: [EXTERNAL] SSL/TLS issue with FTP
Our hosted FTP server must have updated the certificate over the weekend. We are not unable to connect using
FTP RMTSYS(myftpserver) SECCNN(*SSL)
The error is
234 AUTH TLS successful
The server's certificate is not signed by a trusted certificate authority.
Do you want to trust the server's certificate temporarily in this session? (y/n)
Secure connection error, return code 6000
Connecting from a PC works just fine. The CA is "Let's Encrypt".
In DCM, I've populated all of the Let's Encrypt CA's along with ISRG Root 1 and 2.
What am I missing?
