Connection to the Mobile Device Manager Plus server is not secure

Problem

The connection to the server shows "Your connection is not private" despite enabling https communication.

Cause

There are three possible reasons for this error to pop-up.

1. If the server host name is not listed under the (Subject Alternative Name) SAN name of the certificate.





2. If the validity period of the certificate uploaded has expired.





3. If the trusted root certificate is not present on the computer using which the server is accessed.

Resolution

1. If the server host name is not available inside the certificate, users can use the available SAN entries or upload a certificate with the host names under SAN values required for accessing the server.
2. For certificate expiration, users should upload a new certificate.
   Note:The certificates should have a validity period of 397 days maximum. Visit this page to learn how to generate a certificate.
