I have very little knowledge about web hosting and configuration.
I've managed to get myself through some tutorials and have successfully setup an ubuntu home server running Apache. I have a web host and have gotten a website up and running and accessible on the internet. I got SSL certificates through Let's Encrypt and it is working and the renewal automation is working also.
I can go to mywebsite.com and it will convert it to https://mywebsite.com and show it is a secure connection. I do have some services on my server that I access by using the port it runs on. For instance one service runs on port 1000 and I can access it from anywhere via mywebsite.com:1000, but when I do so I get a warning that it is not a secure connection.
I'm sure I have some setting incorrectly setup or i'm doing this wrong. I have multiple different services I can access this way, and all of them do the same thing when accessing through the port. How would I go about fixing this to where they are secure sites? Or what would this even be called so I can look into it more?
