It used to work before on port 80 with my other website. I don’t remember how I set it up exactly but now I follow guide to setup Let’s encrypt and it only make change to like 3 line and when I run ./launcher rebuild app, I got errors saying that the 443 is already in use???
From google result, they require to turn off that 443 but that 443 is already serve by my main website. Like I’ve mentioned, I used to get the port 80 errors before the let’s encrypt and I don’t remember what I’m doing to fix the problem with dicourse + my website.
