    Hi Jim,

    Ever since I updated to Ventura, I have not been able to properly connect to Fetch anymore. Checked if it was a firewall or password issue, but it doesn't seem like it. And the rest of the organization who uses Fetch are not experiencing the same issues. I've checked with our admin team and everything seems to be working properly on their end too.

    It tells me: "SFTP connection to "" could not be opened because the connection to the SFTP server could not be established or was lost. Try again, or contact the server administrator to verify that you have the correct hostname, username, password, and authentication method, and that the server is running. Server responded: "/Unable to negotiate with port 22: no matching host key type found. Their offer: ssh-dis, ssh-rsa"

    Any idea what this could be?

    The problem is that by default Ventura does not use the host key algorithm used by your SFTP server (Apple made this change to improve security). You may want to ask your SFTP server administrator to upgrade to support newer host key algorithms. Otherwise you can work around this change by doing the following:

    1) Choose Utilities from the Go menu in the Finder
    2) Open Terminal
    3) Enter the following (replacing HOSTNAME with your server's hostname):

    echo -e "\nHost HOSTNAME\nHostkeyAlgorithms +ssh-dss\n" >> ~/.ssh/config

    and press Return.

    Please let me know if that does not work.
