This works!!! Thank you, my friend!! I was stuck on this for almost a week!! But then that’s while taking care of a 2yr old and a 6mths old.
Regarding Deodance’s “object reference not set to the instance of an object” error. It’s because you imported the .cer file, import the .p12 instead and it will just ask for the password.
Thanks again Darthlogan, your explanation is concise!
