404 Not Found with Let's Encrypt for NGINX and Learning Locker
December 26, 2019 02:02PM
Hello,

I installed Learning Locker (https://docs.learninglocker.net/guides-installing/) on a Google Cloud VM and verified that everything works for HTTP, but will need to set up HTTPS to send statements. I followed the instructions here https://www.nginx.com/blog/using-free-ssltls-certificates-from-lets-encrypt-with-nginx/ to create a Let's Encrypt certificate, but am getting stuck on Step 2.

It says to create a conf file for my domain name, but when I do that then navigating to my domain gives me a 404 Not Found error. I suspect that this is due to Learning Locker having its own conf file already (learninglocker.conf).

Does anyone know how I can resolve this issue? I've posted the learninglocker.conf file below in case it helps.

learninglocker.conf:

server {
listen 80 default_server;
listen [::]:80 default_server;
server_name myserver.com; // removed just for this post
server_tokens off;

access_log /var/log/nginx/access.log;

}

}

I figured it out. I just needed to place the certificate info into the learninglocker.conf file (inside the server block) and not have it in the domain-name.conf.
