403 Error

[AWS2P]

it almost sounds like the nginx config has become fubar

As i can sleep with more knowledge,could you explain what "fubar" means? i've searched to translate in google with no result

Haha. Just means it is messed up or corrupted.

out of working order; seriously, perhaps irreparably, damaged.

But - the actual letters translate to something on their own:

Yes the https option is at the top of the config file

Do you have shadow copies enabled on the pc you could try restoring that file? Are you doing a full imagine backup of that pc?

Not familiar on how to dig down on Windows but I found an C:\Program Files\3CX Phone System\Bin\nginx\conf\nginx.conf file containing the following:

allow 192.168.0.0/16;
allow 172.16.0.0/12;
allow 10.0.0.0/8;
allow 127.0.0.1;
allow ::0/0;
deny all;

It seems it is correct in allowing. Do you think the server is calling the incorrect file? Where does it request this file in the system? Also, in your file does it have headers for https? Or only http header?

If you use notepad++ to open this file and from line 42-67 you should have the following:

Pay attention to change your FDQN

   server {
        add_header X-Frame-Options "SAMEORIGIN";
        listen 5000;
        listen [::]:5000;
        server_name <YOUR3cxFDQN>;
        server_tokens off;

        access_log off;
        error_log nul crit;

        allow 192.168.0.0/16;
        allow 172.16.0.0/12;
        allow 10.0.0.0/8;
        allow 127.0.0.1;
        allow ::0/0;
        deny all;

        client_max_body_size 300m;

        location /user_images {
            include "shared-headers.conf";
            expires 1y;
            add_header Pragma public;
            add_header Cache-Control "public";
            root "C:/ProgramData/3CX/Data/Http/wwwroot";
        }

Then lines 118-150

Restart NGINX service.
