Hi,
I have just brought the new version 3.7.5. I was using an old before, but I get the same error.
Could not negotiate key exchange algorithm
If I use putty it works, see below.
The server has changed the to use 'Curve25519'. This should be working, but when I check the 'KeyExchangeList' from the program I old get this:
diffie-hellman-group-exchange-sha256,
diffie-hellman-group-exchange-sha1,
diffie-hellman-group1-sha1,
diffie-hellman-group14-sha1,kex-strict-c-v00@openssh.com
Please help ASAP, as we have a production system not working for a lot of users.
