This site can not be reached! ... For additional help, contact the MainWP Support

I have a new website, it runs on its own toort server with nginx as the web server. The Main WP Child-Plugin reports “pass” everywhere in the settings. A connection test from the MainWP server dashboard reports a status of 200 ok. When I want to add the new page I get the message:

This site can not be reached! Please use the Test Connection feature and see if the positive response will be returned. For additional help, contact the MainWP Support.

In my analyzes I cannot find any clues as to the cause.

Nginx, mysql 8.x, WP 5.6.1, PHP 7.4.3

All other security plugins and all other WP plugins have also been deactivated. Unfortunately without success. In addition to port 443 or 80, is another port required? SSH is not running on port 22 on the server.
Do I need a special nginx site-configuration?

I would be happy to receive support and a tip or work-around.

Best Regards
Dirk

Hello Bogdan,

thank you for your support. Enclosed you will find the desired system report from the server. There is no possibility to create a report for the MainWP community on the client.

Hi Dirk, thanks for getting back to me.

I checked the system reports, on the Dashboard side, I can’t see anything unusual.
However, on the child site side, I see that Self-connect test fails, which makes me believe that the same problem prevents your dashboard from connecting to the child site.

Hello Bogdan,

I have a root server that shouldn’t run through a cloud proxy. I have written to the support of my hoster and asked to confirm this acceptance or, alternatively, to provide further information.

The site runs through an Nginx server and not an Apache server. So I don’t have a .htaccess file.

Here are the most important configuration entries:
/etc/nginx/nginx.conf:

    # Basic Settings
    ##
    client_max_body_size 64M;
    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;
    # server_tokens off;

    # server_names_hash_bucket_size 64;
    # server_name_in_redirect off;

sites-available/sites.conf:
server {
listen 80;
listen [::]:80;
server_name academy.xxxxxxxxxxxxx.de;
return 301 https://academy.xxxxxxxxx.de;
}

server {
# SSL configuration
#
listen 443 ssl;
listen [::]:443 ssl;

    include snippets/academy-unternehmer.conf;
    include /etc/letsencrypt/options-ssl-nginx.conf;
    #
    # Note: You should disable gzip for SSL traffic.
    # See: https://bugs.debian.org/773332
    #
    # Read up on ssl_ciphers to ensure a secure configuration.
    # See: https://bugs.debian.org/765782
    #
    # Self signed certs generated by the ssl-cert package
    # Don't use them in a production server!


    root /var/www/academy;

    # Add index.php to the list if you are using PHP
    index index.php index.html index.htm;

    server_name academy.xxxxxxxxx.de;

    location = /favicon.ico {
        log_not_found off;
        access_log off;
    }

    location = /robots.txt {
            allow all;
            log_not_found off;
            access_log off;
    }

    location / {
        try_files $uri $uri/ /index.php$is_args$args;
    }

    location ~ ^/wp-json/ {
        rewrite ^/wp-json/(.*?)$ /?rest_route=/$1 last;
    }

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_intercept_errors on;
        fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
  }

    location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
            expires max;
            log_not_found off;
    }

I checked the certificate and it shows no errors.

Another note, the domain is with another provider and is forwarded to the server via DNS A record.

Best Regards
Dirk
