Get-TlsCertificate

This PowerShell script is helpful for troubleshooting TLS issues associated with public websites or other HTTPS services like TLS VPNs. Using this script, administrators can view and optionally save the certificate returned during the TLS handshake. Administrators can confirm certificate details and perform revocation checks, if necessary. The script also reports the TLS protocol version and cipher suite negotiated for the session. Note that the reported TLS version is the highest version mutually supported by the remote host and the local operating system, not a complete list of protocol versions the remote host supports.
