The software vendor has a license for the WindX 2017 client. I don't know that they have or are willing to license the newer client, which I'm sure will work.

I'm stuck with dumbing down the cryptography settings on the server until it will work with 2017.

Hello,

My client has 2017v14 licensed through a third party. They're upgrading to a new RedHat 9.x server.

The WindX PxPlus 2017 client works with the (much) older RedHat server, but is getting the following error on the new server just after entering the username into the terminal login prompt:

Couldn't agree a key exchange algorithm (available: curve25519-sha)

I'm assuming that the new server did not enable the KEx or SSH ciphers that come with 2017. Is there a list of those somewhere? I didn't see them in the support docs.

Or if it's something else and you know the fix, I'll take that, instead.

Thanks,

Chris
