Following instruction on this page you can test if your client has support for a necessary cipher suite 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 / TLS_AES_256_GCM_SHA384 indicates that the host OS supports TLS_AES_256_GCM_SHA384TLSv1.3 which is one cipher suite that our servers also support.
TIP: Version of your integration engine running on the given host might not support any of the cipher suites that our servers support.
NEXT: Consult documentation of your integration enginge to see what cupher suites it supports.
TIP: client software might be outdated or missing security updates (can be OS and/or integration engine version).
NEXT: Explore ways to update your client software and/or its runtime environment.
