User Configuration\Administrative Templates\Zoom Meetings\Zoom Meetings - Default Settings (users can override)\Zoom General Default Settings Description
Default policy is disabled. If this policy is enabled, when the client resolves both IPv4 and IPv6 addresses and the IPv6 TLS connection fails, the client will retry the connection using IPv4. If this policy is disabled, the client will not perform this IPv4 retry for IPv6 TLS errors. If this policy is not set, client will use the default setting.
