If your web server uses apache service and use Nginx as a reverse proxy, Nginx configuration file similar to the following example:

## Basic reverse proxy server ##

#Hot swap conf ->

upstream 81Port_hot_swap_class {
        server ip:81 weight=10 max_fails=3 fail_timeout=30s; #Apache
}
## Start ##
server {
    listen *:81;
    server_name  domain;
 
    access_log  logs/domain.access.log  main;
    error_log  logs/domain.error.log;
    root   html;
    index  index.html index.htm index.php;
 
    ## send request back to apache ##
    location / {
        proxy_pass  http://81Port_hot_swap_class;
 
        #Proxy Settings
        proxy_redirect     off;
        proxy_set_header   Host             $host;
        proxy_set_header   X-Real-IP        $remote_addr;
        proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
        proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
        proxy_max_temp_file_size 0;
        proxy_connect_timeout      90;
        proxy_send_timeout         90;
        proxy_read_timeout         90;
        proxy_buffer_size          4k;
        proxy_buffers              432k;
        proxy_busy_buffers_size    64k;
        proxy_temp_file_write_size 64k;
   }
}
## End ##

Solution
In order to open WordPress installation directory, wp-admin/includes/class-wp-list-table.php
Find the following code

$current_url = set_url_scheme( 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'] );

replaced the $ _SERVER ['HTTP_HOST'] by URL.
