Failed to reconcile key exchange method with Mina deployment

I come across this message when deploying with Mina, but not sure why Git cannot execute the repo.

I tried switching sshd_config due to the message Unable to negotiate a key exchange method, but still can't figure out what is going on. Thanks for the help.

The problem is that your local SSH client and the remote endpoint in GitHub cannot agree on a common key exchange method.

This will happen when you dig into the set of available key exchange methods or use a very old and outdated SSH client that does not support any method that is still considered safe.

, GitHub: .

, SSH:

export GIT_SSH_COMMAND="ssh -vv"

, config_ssh ~/.ssh/.config, . , Host *:

# Github needs diffie-hellman-group-exchange-sha1 some of the 
# time but not always.
Host github.com
    KexAlgorithms curve25519-sha256@libssh.org,diffie-hellman-group-exchange-sha256,diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1
