Hi,
Do the Poly VVX series support SCEP over HTTPS? For example, most cloud PKI providers (like Scepman, Keytos etc) use HTTPS for their SCEP URL.
When attempting to use an HTTPS url for SCEP, the initial connection is successful and it downloads the SCEP CA certificate (which can be seen under "Auto Prov CA" and "Certificates installed with the help of SCEP").
On the next step it submits the SCEP request and appears to fail to connect to the server as it looks like its trying to only use the SCEP CA certificate to verify the cert (in the case of the log below scep.msappproxy.net is using a Digicert CA cert) rather than using the other CA certificates built into the phone. Is this because the "Auto Prov Profile" only looks at this cert?
Current phone firmware: 6.3.1.11465
