ssh key exchange algorithm

After securing my ssh server to only accept more recent algorithms, I can no longer access my git repository on windows.

I don't know what "available" means. Does that mean what it thinks it can support, or what the remote side supports?

I am using puTTY 0.70, and I can connect to that server. I've tested on the command line with plink and have no problems. SourceTree is configured to use plink, and using Git from the command line works fine.

I know my SSH server supports all those listed, but also diffie-hellman-group-exchange-sha256.

This is in my sshd_config. It's OpenSSH Server 7.4 on Debian.


If I add diffie-hellman-group14-sha1 to the Key exchange algorithm list, it works, but I don't want to enable this algorithm.

I'm using I've also tried the update to 2.3.1, but that doesn't change anything.
