SSL Does not work

I have followed the video, read a lot of docs, and installed a wild card certificate from Global Sign. It even shows the certificate installed and expiring in 118 days. But the browser will not accept SSL and keeps throwing error that site is not secure. Frustrated that something as simple as SSL should work out of the box, but see that is an issue with a lot of folks. Tried this product and Cyber panel manager 2 years ago, as I wanted to move away from Plesk. But found it had a lot of end user features missing and was not very user friendly. Now making another attempt, but it is frustrating. Any ideas?
