When using the UTunnel VPN client application on a Windows PC, the CA certificates will get automatically downloaded and installed for users with administrator permission. But, non-admin users will not be able to connect to the VPN server until they manually download and add the CA certificate as a trusted root authority.
This help guide details on how to download and manually install CA Certificate on Windows.
Only VPN server owners or admins will be able to download the CA certificate for a particular server. Please follow the steps here to download the certificate.
