Primary Issue: cpanel tls cipher/protocol

Error Message: This connection is untrusted.

The SSH connection to “” failed because of an error:

(XID pe7ddc) The system stopped waiting to connect to “” on port “22” after 15 seconds.

The system also attempted to avoid SSH via a direct connection to WHM on “”. However, the connection failed its TLS validation (OK). Because of this, “” cannot prove its identity, and an attacker may be impersonating that server.

It is not recommended that you continue. You should fix the TLS verification problem with “” before you try again. For more information, read our SSL troubleshooting documentation.

If you continue, the system will create an insecure connection to “” to verify its cPanel & WHM version information. The version of cPanel & WHM on “” must be version 90 or later.
