Trying to do Newsletters Over HTTPS

I’m trying to do newsletters over HTTPS, but it’s not working out so great. I even made sure to tell Softacuolous to use HTTPS, but still nothing. I made sure that the code was correct. Nothing. I made sure of everything, but it’s not working. I even took a screen recording showing what I did from start to finish. If someone can help me here that would be awesome. Any and all help is appreciated!

Thank you in advance!
