Access denied after installation

Hi,

I recently installed Foswiki on a Ubuntu 16.04 in DigitalOcean using NGINX. But after doing for the first time sudo service foswiki start, I get an Access denied. In the webpage, I don't know why I get this error. Can someone help me?

This is really tough to debug in a topic like this.

How did you configure nginx? There is a more recent config at System.FastCGIEngineContrib#Nginx that will be supplied with the upcoming 2.1.4 But the configs atSupport.FoswikiOnNginx should also work fine.
Did the foswiki service actually start and stay running? Usually if it's not up, then nginx will reply with a 503 gateway unavailable.
There are some minor script updates also planned for 2.1.4. See the source at https://github.com/foswiki/distro/tree/Release02x01/FastCGIEngineContrib/tools - but these probably would not cause an access denied message.
Check your Nginx logs - it is showing any reasons for the denied message.
Can you reach any pub/ files. For ex: yoursite.com/pub/System/ProjectLogos/foswiki-logo.png

Hi, thank you for your help, these are the contents of the nginx configuration:

    listen      80;

    location ~ ^/([A-Z_].*)$ {

       }

    location ~ (^/lib|^/data|^/locale|^/templates|^/tools|^/work) {
        deny all;
    }

This is the status of the foswiki service:

Looks like I'm able to reach the pub/files:

Looks like your service is not remaining running! It's showing Tasks:0, and active (exited) status. Here is what a running status would look like:

Take a look at the results from journalctl -xe. You should see the AUTOCONFIGURE bootstrap messages, and/or errors that might say why the back end is not running.

I have been able to fix the previous issue as the error statement suggests:

May 21 01:14:39 HatAndSlash foswiki[21575]: bind/listen: Address already in use

The socket that foswiki expected to listen was in use, so I fixed that by stopping the service that was using it(such service was not necessary)

And now I'm able to see the wiki startup page
