To enhance security and address potential vulnerabilities (such as GHSA-3m6q-h5gj-7mrw), the Secure Source Manager Git-over-SSH server configuration has removed support for several legacy and insecure SSH algorithms.

SSH clients must support one or more of the following modern algorithms to connect:

• Key Exchange Algorithms: curve25519-sha256, diffie-hellman-group14-sha256 • Ciphers: chacha20-poly1305@openssh.com, aes128-ctr, aes192-ctr,aes256-ctr, aes128-gcm@openssh.com, aes256-gcm@openssh.com • MACs: hmac-sha2-256-etm@openssh.com, hmac-sha2-256

Users with old or non-standard SSH clients lacking support for these algorithms will be unable to connect using SSH for Git operations. Ensure your SSH client is up-to-date.
