Hi, thanks for your response.
This is my conf from /etc/nginx/nginx.conf

user www-data;
worker_processes 1;
pid /var/run/nginx.pid;

events {
    worker_connections 1024;
}

http {
    include /etc/nginx/conf-enabled/*.conf;
    include /etc/nginx/sites-enabled/*.conf;

In the 00-default.conf I have this:

server {
    # Listen on ipv4
    listen 80;

    # Listen on ipv6.
    # Note: this setting listens on both ipv4 and ipv6 with Nginx release
    #       shipped in some Linux/BSD distributions.
    #listen [::]:80;

    server_name _;

    # Redirect all insecure http:// requests to https://
    return 301 https://$host$request_uri;
}

In the 00-default-ssl.conf I have this:

server {
    listen 443;
    server_name _;

    root /var/www/html;
    index index.php index.html;

    include /etc/nginx/templates/misc.tmpl;
    include /etc/nginx/templates/ssl.tmpl;
    include /etc/nginx/templates/iredadmin.tmpl;
    include /etc/nginx/templates/roundcube.tmpl;
    include /etc/nginx/templates/sogo.tmpl;
    include /etc/nginx/templates/netdata.tmpl;
    include /etc/nginx/templates/php-catchall.tmpl;
    include /etc/nginx/templates/stub_status.tmpl;
}

Then I have other virtual ones that were working until I installed iredmail, since I install when I call any virutal the webmail of iredmail always speaks to me.
I do not see anything more than this.

Thanks for your answer

Yes I have
They are the 3 that I post here.
The default ones are .conf, the other one that I use for odoo is not, I named it only "odoo".
I had already tried with the name of odoo.conf and it did not work either

Not sure whether to add to an existing post or open a new one, I am stuck at the same point as ffrcaraballo
https://forum.iredmail.org/topic15142-p … nginx.html

On my iRedmail / nginx server mx.domain.com and domain.com I would like (as under apache previosuly) host a variety of php and other scripts in a number of (sub)directories. Other than https://domain.com/iredadmin/ everything seems however to redirect to https://domain.com/mail.

My nginx.conf is standard, I added a
/etc/sites-available/myOwnWeb.conf, add symlink, added webspace /var/www/html/htd/hallo.html

"# HTTPS
server {
    listen 443 ssl;
    server_name domain.com/htd;
##    index index.php index.html;
#    include /etc/nginx/templates/misc.tmpl;
#   include /etc/nginx/templates/ssl.tmpl;
  #  include /etc/nginx/templates/iredadmin.tmpl;
  #  include /etc/nginx/templates/roundcube.tmpl;
  #  include /etc/nginx/templates/sogo.tmpl;
  #  include /etc/nginx/templates/netdata.tmpl;
  #  include /etc/nginx/templates/php-catchall.tmpl;
  #  include /etc/nginx/templates/stub_status.tmpl;
    root /var/www/html/htd;
}"

I just took it from 00-default-ssl.conf, hoping it would give me my own webspace while keeping the roundcube mail and the iredadmin, but no luck. error.log "... server name "domain.com/htd" has suspicious symbols". Could anyone help me with my first nginx steps?

Understood, could you point to a tutorial on how to make websites work on the same server as iredmail please.

Check file /var/www/html/index.html.

@boegenhold
can you try this

ln -s /etc/sites-available/myOwnWeb.conf /etc/sites-enabled/001-myOwnWeb.conf

nginx -t
nginx -s reload

Did you try to empty web browser cache and check again?

edit

 server_name _;

change

server_name orherdomain.com;

nginx -t
nginx -s reload
