Default “Welcome to nginx“ page displayed instead of Matrix Synapse web client interface !

Hello,

Synapse homeserver installation was achieved with test domain name and environnement (remote VPS), following D.O tutorial. Steps including NGINX CONFIGURATION were done **as root **(step 5 was skipped for now) :

https://www.digitalocean.com/community/tutorials/how-to-install-matrix-synapse-on-ubuntu-16-04

However I can’t prevent Nginx displaying default 'WeLCOME TO NGINX‘ page as result for calling URL ‘https://boggle.tcei-designlab.net‘ (I faced the same issue earlier while trying to install Synapse homeserver on OS Ubuntu 18.04), although the installation was achieved without bugs.

Please see lists of additional steps I have done trying to solve this issue :
• I did remove ‘/ect/nginx/sites-enabled/default‘ file and get nginx successfully restarted behind • I gave full permissions over ‘/html/index.nginx-debian‘ folder and file • I did verify DNS Zone : ‘A‘ entries pointing to IPV4 VPS address for both ‘boggle.tcei-designlab.net‘ and ‘www.boggle.tcei-designlab.net‘ • I did verify syntax error with command ‘sudo nginx -t‘ (none was found) • I did verify Vhost config file :

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

root /var/www/html;
index index.html index.htm index.nginx-debian.html;

server_name boggle.tcei-designlab.net www.boggle.tcei-designlab.net;

location /_matrix {
    proxy_pass http://localhost:8008;
}

location ~ /.well-known {
    allow all;
}

}

Any help would be well appreciated ! Please let me know if some file content screenshots could help tracking what may have gone wrong !
