Description (last modified by Maxim Dounin)

I've created a cyrillic domain name and want to use nginx to serve simple html files. I get 400 when I try to open the domain. No useful information in logs is shown.

I copied nginx.conf from an ASCII domain I had, but that didn't work. Also permissions to my public_html are same. I restarted nginx, that didn't help (-s reload and also killing the process).

more error.log

2016/03/13 09:18:04 [notice] 16418#0: signal process started

(note that was some time before my attempt to connect).

I know that 400 may be connected with cookies, but I used wget, curl, Opera and Firefox to open that page with the same results.

My nginx.conf:

server {
    server_name людмилавахнина.рф;
    charset     utf-8;
    #source_charset     utf-8;
    error_log /var/log/nginx/lvahnina_debug.log debug;
    error_log /var/log/nginx/lvahnina_error.log info;
    # these two files are empty. No errors.
    root /home/nikitenko/lvahnina/public_html;

    location = / {
        try_files /index.html =404;
    }

    location = /index      { return 404; }

    location / {
        try_files $uri.html =404;
        #try_files $uri.html;
    }
}

I don't have much memory on the machine, but probably that should be enough,

$ free
              total        used        free      shared  buff/cache   available

The server_name in the configuration snippet you've provided is wrong. You should use ​punycode-encoded name instead, xn--80aaagiydsciqb5hsf.xn--p1ai (as seen in the Host header of the HTTP request).

This is likely what causes your other issues. Note that according to the log provided the error is returned no by nginx but by your backend server. Likely this backend is configured in the default server{} block - as no matching server_name is found, the default server{} block is used by nginx to process the request.

Thank you. But I use another cyrillic name as UTF-8 on the same system (but with django), and it works fine. I'll see whether your suggestion will work.

Replying to ynikitenko@…:

Thank you. But I use another cyrillic name as UTF-8 on the same system (but with django), and it works fine. I'll see whether your suggestion will work.

I guess that "another cyrillic name" is used in the default server block. See ​the documentation for details.

comment:4 by ynikitenko@…, 8 years ago

Many thanks for the explanation! Now it works. However, it seems that there is nothing on punicode in nginx docs: see ​https://www.google.ru/search?q=+punicode+site:nginx.org/en/docs
Will you propose an improvement for the documentation or should I do that?

The other site works fine, its nginx conf is the following (it's not a default server block, it's from sites_available/):

# the upstream component nginx needs to connect to
upstream django {
    server unix:///home/nikitenko/arsenia/arsenia.sock; # for a file socket
    # server 127.0.0.1:8001; # for a web port socket (we'll use this first)
}

# configuration of the server
server {
    # the port your site will be served on
    #listen      8000;
    # the domain name it will serve for
    server_name арсенияникитенко.рф; 
    charset     utf-8;
    #source_charset     utf-8;
    error_log /var/log/nginx/debug.log debug;
    error_log /var/log/nginx/arsenia_error.log;

    # max upload size
    client_max_body_size 75M;   # adjust to taste

    # Django media
    # note: on localhost it's called upload/, so change its name to медиа/ !
    location /медиа/ {
        root /home/nikitenko/arsenia;  # your Django project's media files - 
amend as required
        # rewrite ^(.+)/+$ $1 permanent;
        try_files $uri =404;
        #alias /home/nikitenko/arsenia/upload;  # your Django project's media
 files - amend as required
    }

    location /static {
        # rewrite ^(.+)/+$ $1 permanent;
        root /home/nikitenko/arsenia;  # your Django project's media files - 
amend as required
        try_files $uri =404;
    }

    # Finally, send all non-media requests to the Django server.
    location / {
        uwsgi_pass  django;
        include     /home/nikitenko/arsenia/uwsgi_params; # the uwsgi_params 
file you installed
    }
}

I think that if one config works fine and another doesn't than that is probably a bug (maybe both shoudn't work or both should work).

Dear nginx programmers, I suggest to improve the documentation and make the behaviour of nginx prohibitive with non-punicode domains.
Please read the previous comment for details.
