Hi @rg305,
Thank you so much for your help on this. I have tried the approaches you have suggested but they all lead to the same error of 503 which I have been getting from the start. As you have suggested, I am looking and staring hard at my nginx config file now. Will definitely update if there is progress. Thanks!

nginx config:

server
{
#makes sures all URL access are https
listen 80;
listen [::]:80 default_server ipv6only=on;
return 302 https://$host$request_uri;
}

server
{
listen 443;

server_name tite.rdc.nie.edu.sg;

location /
{
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-NginX-Proxy true;
    #For Each mgb instance config file, the port set to listen is used for the following line
    proxy_pass http://localhost:8080/;
    #proxy_pass http://118.201.204.72:8080/;
    proxy_ssl_session_reuse off;

    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header Host $host;

    proxy_cache_bypass $http_upgrade;
    proxy_redirect off;
}

}
