 ## Compatibility with Minimum TLS Version
 
-When you adjust the setting used for your domain's [Minimum TLS Version](/ssl/edge-certificates/additional-options/minimum-tls/), your domain only allows HTTPS connections using that TLS protocol version.
+When you adjust the setting used for your domain's [Minimum TLS Version](/ssl/edge-certificates/additional-options/minimum-tls/), your domain only allows HTTPS connections using that TLS protocol version. As explained in [About cipher suites](/ssl/edge-certificates/additional-options/cipher-suites/#related-ssltls-settings), although configured independently, cipher suites and TLS versions are closely related.
 
-This setting can cause issues if you are not supporting TLS 1.2 ciphers on your domain. If you experience issues, review your domain's [Minimum TLS Version](/ssl/edge-certificates/additional-options/minimum-tls/) setting and Cloudflare's [supported ciphers list](/ssl/edge-certificates/additional-options/cipher-suites/supported-cipher-suites/).

 ## Test supported TLS versions
 
-To test supported TLS versions, attempt a request to your website or application while specifying a TLS version.
-
-For example, use a `curl` command to test TLS 1.1 (replace `www.example.com` with your Cloudflare domain and hostname):
-
-```sh
-curl https://www.example.com -svo /dev/null --tls-max 1.1
-```
-
-If the TLS version you are testing is blocked by Cloudflare, the TLS handshake is not completed and returns an error:
