Hello @sakuraime and welcome back to Microsoft Q&A.

When a client and server start to connect, one of the things they do, is negotiate an encryption and key exchange algorithm. There exist many algorithms in the world, and not every client or server supports all of them. In order to use one, both the client and server must have one in common. This error message suggests they could not find common ground.

There are several pieces I recommend checking. One of them is the TLS/SSL versions. Another is whether the server accepts SSH key exchange algorithms, specifically diffie-hellman-group.

@sakuraime
For the key-exchange algorithms you would have to ask the server administrator.

For SSL/TLS, if you have any tools installed locally, for connecting to said server, I would recommend poking around in their settings.

There is one other possibility, a mixup of FTPS , SFTP , and FTP over SSH.
