Temporary test domain name or way to achieve this

A better option might be to simply create a symbolic link.

A symbolic link is part of your file system (nothing to do with Apache or nginx).

It creates a “virtual” directory which maps to a directory elsewhere in the file system.

You would run this via the command line (make sure the newsite folder doesn’t already exist):

ln -s /var/www/newsite.com /var/www/caribbean-diving.com/newsite

This creates a “vitual” link under /var/www/caribbean-diving.com/newsite which maps to /var/www/newsite.com

Anyone visiting http://caribbean-diving.com/newsite will see the contents of /var/www/newsite.com

Out of interest what operating system are you using locally on your own computer?

If you’re using Windows you can edit the file C:\Windows\System32\drivers\etc\hosts and add a line like this:

2.2.2.2 testdomain.com

Replace 2.2.2.2 with the IP address of your droplet.

testdomain.com will then map to your droplet from your local work station, bypassing any external DNS lookup.

Setup a new virtual host under sites-enabled.conf for testdomain.com and away you go.

In my case what seems to have been lacking is a default server and now it seems to be working and what @DigitalCarrot would have got had I posted my server block code…many thanks to you @DigitalCarrot

SO in my default site block I now have this

server {
        listen 80 default_server;
        listen [::]:80 default_server;

Vs

server {
        listen 80;
        listen [::]:80;

Now when I use the IP address remotely I can access what this default site points to…
