SFTP Error 1051

#1 Post by B3Technology » 2024-03-18 15:46

Hello All:

This is my first post to this community, and I hope someone can help me out.

We just installed the FileZilla Server Pro software and got everything setup as near as we can tell for us to be able to allow SFTP connections.

We have tested our connection from outside using VanDyke SecureFX software and everything works fine.

When our vendor attempts to connect using Cleo VLTrader we are getting the error "Unrecoverable error cannot match key algo with peer (-1051)]". When talking with the vendor they support only the following Cipher Algorithm:

3des-cbc
aes128-cbc
aes128-ctr
aes192-cbc
aes192-ctr
aes256-cbc
aes256-ctr
arcfour128
arcfour256
blowfish-cbc
cast128-cbc
twofish128-cbc
twofish192-cbc
twofish256-cbc.

Nothing seems to allow the connection. What am I missing?
