NSS Certificate install error

Hi All,

I am trying to install the NSS certificate on the NSS server (esxi) to start the nss functionality and getting he below error:

////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
Please enter complete path to the certificate bundle(.zip): /usr/home/zsroot/
tar: Unrecognized archive format
tar: Error exit delayed from previous errors.
////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

Note:
.zip - Downloaded from ZIA portal under NSS servers
path - on the NSS server “/usr/home/zsroot/NssCertificate.zip”

FYI, I tried extracting the certificate file separately, in a folder created a new .zip file and try, but still the same error
