.NET clickonce download error

I used clickonce in .NET to create an install and pushed it to the server.  When clicking on the link I receive the below error.

Downloading https://xxxxxcom/xxxxx/xxxxx.application did not succeed.
+ The request was aborted: Could not create SSL/TLS secure channel.

Any ideas?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Is https://xxxxxcom/xxxxx/xxxxx.application certificate valid?

Is the client computer's time correct?

Is the root certificates on the client up-to-date?

Try this
// using System.Net;
ServicePointManager.Expect100Continue = true;
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
// Use SecurityProtocolType.Ssl3 if needed for compatibility reasons

Does the certificate have to be installed on the client where the app will install?

Is it a public cert?

Should only be required if it is a private or PKI cert
