SFTP file transfer issue- Mismatch between the encryption supported by PeopleSoft, and SFTP server

When trying to SFTP files to a SFTP server from a PeopleSoft PT8.55 application, the transfer will fail. The PeopleCode trace file shows: "FTP library Error code : 2 - Failed initialization". The FILETRANSFER log will show this error: "curl: (2) Failure establishing ssh session".

We found exact error in Oracle support and the cause for this is Peopletools 8.55 doesn't support CTR encryption technique and it was added in tools 8.56.

Unfortunately all our servers were setup with the newer encryption (list mentioned below, in which CTR is one of them) techniques and as per the organization security & compliance we cannot downgrade them.

Ciphers supported by JPMC: aes128-ctr,aes192-ctr,aes256-ctr,aes128-gcm@openssh.com,aes256-gcm@openssh.com,chacha20-poly1305@openssh.com

We are almost at the end of our application upgrade project with our newer tools version (PT 8.55) and the golive date is scheduled end of this month, this issue has become show stopper now. As we cannot upgrdae our tools to 8.56, can we get some peopletools 8.55 patch/fix that can support any one of the above JPMC ciphers
