Zoom Security Warning - Untrusted Server Certificate

An Untrusted Server Certificate error indicates that the certificate (one of the elements proving that data is only going to trusted locations online) that the Zoom application is seeing is ​not​ the certificate that was expected. This can happen for a variety of reasons.

For information on the untrusted server certificate, see Zoom's article titled, 'Zoom Untrusted Server Certificate issues':
