Answer 1

I think you have updated php execution time in php config but what about Nginx config?
Try updating your Nginx Config :
Step 1 : Updates for your website test.com
vim /etc/nginx/sites-available/test.com
Step 2 : Updating Execution Time
location ~ \.php$ {
include /etc/nginx/fastcgi_params;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_read_timeout 300;
}
Step 3 : Don't forget to reload to reflect changes
service php5-fpm reload
service nginx reload
Hope this helps.

I'd check in the following order:
1) If php5-fpm is running:
sudo service php5-fpm status
if it returns the process number - try telneting it:
telnet 127.0.0.1 9000
2) If telnet returns connected status - I'd start checking the /etc/nginx/sites-enabled if the config of your site is there. If it's there - check that the stuff is set up correspondingly...one of the examples of how to set up nginx with php-fpm is here:
https://www.howtoforge.com/installing-nginx-with-php5-fpm-and-mysql-on-ubuntu-14.04-lts-lemp
3) If that is ok - reload the php5-fpm and nginx and check if permissions in your site dir (typically something like /var/www/html/site.com) are set right for user www-data (the default nginx user).
If that is ok - then I can't think of anything more without seeing configs and having fingertips on machine terminal.
Hopefully this helps a bit.

Had this problem on Ubuntu 16.04 with Apache and PHP 7.0. Tried a dozen solutions, which still gave me errors, and then found https://www.howtoforge.com/tutorial/apache-with-php-fpm-on-ubuntu-16-04/ which worked for me. With PHP 7.0 and Apache 2 installed, and as superuser:
apt install libapache2-mod-fastcgi php7.0-fpm
a2enmod actions fastcgi alias
Restart Apache.
And then add the following to a copy of /etc/apache2/sites-available/000-default.conf as a child of <VirtualHost>
<Directory /usr/lib/cgi-bin>
Require all granted
</Directory>
<IfModule mod_fastcgi.c>
SetHandler php7-fcgi.php
Action php7-fcgi /php7-fcgi virtual
Alias /php7-fcgi /usr/lib/cgi-bin/php7-fcgi
FastCgiExternalServer /usr/lib/cgi-bin/php7-fcgi -socket /var/run/php/php7.0-fpm.sock -pass-header Authorization
</IfModule>
In my case, I used a Sites directory in Home instead of /var/www/ and also had inside :
ServerName localhost
ServerAdmin me#myemail.com
DocumentRoot /home/me/Sites
If using a copy of 000-default.conf make sure to disable it with a2disconf and enable your copy with a2enconf.
