That is what I’ve said in my post before: You have installed Lucee without using the default installer, thus all connections are missing. You’ll need to connect apache2 to Tomcat/Lucee manually. The best actual information I can offer you for this purpose at the moment is an awesome post of @derrickpeavy that somehow is a little lost in this forum. You will find good information there and find the steps to create the connection with mod_proxy. Here it is and thanks to @derrickpeavy for the post.

However, there are guides in the docs, but they neee to be updated. I’ve put this already in my “next contrib list”, but I’m very short with time at the moment, maybe somebody can help out also.
