I already added a redirection on my DNS; but I want to hide the ip addresses and port and stay just with the domain name in the browser address bar.
I kind of figured out how to do it with aprende.techo.org (as it is in the 80 port, adding a CNAME instead of the actual redirection will work) but I don’t know what to do with studio.aprende.techo.org given that is not possible to add a port in a CNAME record on my DNS.
@kike.ramirez, the Open edX native installation method sets up an nginx web server with separate virtual hosts for LMS, Studio etc, thereby allowing both sites to be accessed using just the domain names. If you set up and configure SSL for your Open edX instance, the installation method automatically enables SSL for those virtual hosts so that you can access LMS at https://aprende.techo.org and Studio at https://studio.aprende.techo.org.
In this scenario, you just need to have the aprende.techo.org and studio.aprende.techo.org domain names point to the IP address of the server on which the Open edX instance is running, via A or CNAME records.
