Following instruction on this page you can test if your client has support for one of the SSL/TLS versions required by our servers.

On the host that runs your service run the next command:

curl -o /dev/null -s -vvv https://my.patientsknowbest.com

Expected success output

* Trying 35.246.122.93:443... ... * SSL connection using TLSv1.3 / TLS_AES_256_GCM_SHA384 ... * Connection #0 to host my.patientsknowbest.com left intact

SSL connection using TLSv1.3 indicates that your host OS is supports TLSv1.3 which is one of the TLS versions our servers also support.

TIP: Version of your integration engine running on the given host might not support any of the SSL/TLS version that our servers require.

Expected failure output

* Trying 35.246.122.93:443... * Connected to my.patientsknowbest.com (35.246.122.93) port 443 (#0) * ALPN, offering h2 * ALPN, offering http/1.1 * CAfile: /etc/ssl/certs/ca-certificates.crt * CApath: /etc/ssl/certs * TLSv1.2 (OUT), TLS header, Unknown (21): } [5 bytes data] * TLSv1.3 (OUT), TLS alert, protocol version (582): } [2 bytes data] * error:0A0000BF:SSL routines::no protocols available * Closing connection 0
