Something that's bothered me about Untangle for years is my inability to get the HTTPS certificates done properly. I feel like I need a little help with setting it up properly. I would like to avoid the "not secure" all the time on the webpage gui. I know it's dumb, but I feel like it's a failure on my end to properly learn to set it up. So is it possible I could get a little help on it from someone a bit more knowledgeable. I'm not sure if I need to do something through let's encrypt or use a certificate authority.
Thanks!
