How to migrate Apache to Nginx in a new server with new domain?

I’m trying to move a wordpress instalation to a new server.

The old server (development server) had a different domain and a common LAMP stack. In this new server I added an SSL certificate installed nginx instead of APACHE, put PHP7 instead of PHP5 and changed the domain.

I used interconnect/it to change all urls on the database.

The landing page and wp-admin work as expected. But all other links show a nginx not found page.

The error log shows the following:

2016/05/17 10:38:22 [error] 29722#29722: *1 FastCGI sent in stderr: "PHP message: header-1
PHP message: !empty(page_id)90px
PHP message: header-1
PHP message: !empty(page_id)90px" while reading response header from upstream, client: 0.0.0.0, server: host, request: "GET /wp/?custom-pag$

My Nginx configuration:

server {
    listen 80;
    location / {
        return 301 https://$host$request_uri;
    }
}
server {
    server_name www.host.com hostcom;
    listen 443 ssl http2 default_server;
    port_in_redirect off;
    access_log   /var/log/nginx/host.com.access.log;
    error_log    /var/log/nginx/host.com.error.log;

    root  /path/to/root;
    index index.php index.html index.htm;

    [SSL configuration]
    resolver 127.0.0.1;

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

    # Cache static files for as long as possible
    location ~*.(ogg|ogv|svg|svgz|eot|otf|woff|mp4|ttf|css|rss|atom|js|jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|tar|mid|midi|wav|bmp|rtf|cur)$ {
            expires max;
            log_not_found off;
            access_log off;
    }

    # Deny public access to wp-config.php
    location ~* wp-config.php {
        deny all;
    }

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php7-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }

}

What I’m I doing wrong?

Thank you.
