So I did what you said. I changed my port from 127.0.0.1:8088 to 0.0.0.0:8088, installed Rust, compiled the code, and ran it through the Linode instance. I tried to visit the site with my domain name but it said the server refused to connect. Then I tried visiting it directly with Linode's IP address and again I get the message saying the server refused to connect. I also tried it running cargo run --release and there was no difference. What step did I miss? I was under the assumption that I could visit the site afterward.
Edit: It might be the firewall, I'm going to check if it works on a different port number.
Edit: It worked! It's successfully hosting the website. Now I just have to download the database and activate my SSL.
