Yes, and I updated the version box above to show the version of the nightly that I tried

Describe the bug

Using libssh-rs to connect to ABC@relay.ABC.com:22
Error: Connecting to relay.ABC.com:22: Fatal: kex error : no match for method server host key algo: server [ssh-rsa,ssh-dss], client [rsa-sha2-512,rsa-sha2-256,ssh-ed25519,ecdsa-sha2-nistp521,ecdsa-sha2-nistp384,ecdsa-sha2-nistp256,sk-ssh-ed25519@openssh.com,sk-ecdsa-sha2-nistp256@openssh.com]

This error:

Error: Connecting to relay.ABC.com:22:
Fatal: kex error : 
no match for method server host key algo:
server [ssh-rsa,ssh-dss],
client [rsa-sha2-512,rsa-sha2-256,ssh-ed25519,ecdsa-sha2-nistp521,ecdsa-sha2-nistp384,ecdsa-sha2-nistp256,sk-ssh-ed25519@openssh.com,sk-ecdsa-sha2-nistp256@openssh.com]

Means the server only supports security checks using ssh-rsa, or ssh-dss, which the client doesn't support.

The default ssh backend in wezterm is better suited for recent protocols. If you need to connect to a server that only support older protocols, you can try to add this config:

config.ssh_backend = "Ssh2"
