How to check the TLS version of your load balancers

To accurately determine the TLS version of your load balancers, it is recommended that all tests are run against the default domain of your application ([your-application].prod.acquia-sites.com). Using other custom domains, which may or may not be routed through other services (for example a CDN such as Cloudflare) may not garner accurate results.

It is recommended that you use an online tool such as Qualys (https://www.ssllabs.com/) for your tests or alternatively you can use the command line tool nmap like so:

nmap --script ssl-enum-ciphers -p 443 [your-application].prod.acquia-sites.com
