Error number: MY-013746; Symbol: ER_WARN_DEPRECATED_TLS_VERSION_FOR_CHANNEL; SQLSTATE: HY000

Message: A deprecated TLS version %s is enabled for channel %s

Error MY-013746 (ER_WARN_DEPRECATED_TLS_VERSION_FOR_CHANNEL) is a MySQL error indicating that the current TLS version set for the MySQL server is deprecated and needs to be updated to a newer version.

Error MY-013746 is triggered when either a client or a server is using an outdated and insecure TLS version, which might result in compromised connections. This is to prevent a server from being vulnerable to various attacks, such as man-in-the-middle or protocol downgrade attacks.

Common cases where this error might be encountered include when trying to connect to a MySQL server using an outdated client or an outdated TLS version on the server. This error can also occur when using a server configured with the TLS option enabled, but using the wrong version of TLS.

The most common solution to this issue is to check the installed version of TLS, and upgrade it to the latest version available. If the connection is supposed to be secure and encrypted, it is important to make sure that both the client and the server side have TLS and all its versions up to date. On the server side, this can be done by checking the MySQL configuration file and making sure that the “version” option is set to the latest version of TLS, or at least the version supported by the client. On the client side, this can be done by updating the MySQL client to the latest version, or by using an alternative client that supports a modern version of TLS.

If you are using an older version of MySQL, it is also a good idea to check if there is an available patch for the outdated TLS version, and apply it as soon as possible. If that is not possible, it might be necessary to upgrade the MySQL version to a newer one that supports a modern version of TLS.

Ultimately, updating the TLS version is important to ensure the security and integrity of your connection, as well as to prevent possible attacks.
