Re: Drawpile Server Administration using RestAPI through NGINX reverse proxy

***THIS QUESTION IS OFFICIALLY SOLVED.***
I would have deleted/edited posts if I could, but alas I cannot. So I'm posting a final update.
------------------------------------------------------------------------------------------------------------------------------
This is the actual configuration I used for NGINX, located in /etc/nginx/nginx.conf under the line "include /etc/nginx/sites-enabled/*;" See the attached image for proper formatting.

server {
listen 8081;

location / {
proxy_pass http://127.0.0.1:8080/;
proxy_redirect default;
auth_basic "Server Administration";
auth_basic_user_file /etc/nginx/passwords;
}
------------------------------------------------------------------------------------------------------------------------------
The line below is the line I use to insert my desired changes to NGINX by script.

sudo sed -i.bak 's/^ include \/etc\/nginx\/sites-enabled\/\*\;$/&\n \n server {\n listen 8081\;\n \n location \/ {\n proxy_pass http:\/\/127.0.0.1:8080\/\;\n proxy_redirect default\;\n auth_basic "Server Administration"\;\n auth_basic_user_file \/etc\/nginx\/passwords\;\n }\n}\n/' /etc/nginx/nginx.conf
------------------------------------------------------------------------------------------------------------------------------
And this is the final copy of the script I made for creating a drawpile server on the Raspberry Pi 3 running Raspbian Stretch 4.9.
