Error - php7.0-fpm.sock failed [NGINX - Ubuntu Server]

Respected, I’m facing php7.0-fpm.sock failed error from a long time on Ubuntu 16.04.5 LTS (NGINX). Six websites are active on this server.

Kindly check below detailed logs.


2018/09/04 06:25:04 [error] 18209#18209: *362673 connect() to unix:/run/php/php7.0-fpm.sock failed (11: Resource temporarily unavailable) while connecting to upstream, client:, server: [domain_name_hidden].com, request: “GET / HTTP/1.1”, upstream: “fastcgi://unix:/run/php/php7.0-fpm.sock:”, host: “[domain_name_hidden].com”

If reboot the server then websites are working for a limited period (Approximately 5-7 hours). Another fix, I need to restart the PHP FPM through the following command: sudo service php7.0-fpm restart

Please help. Thank you!

I have changed root from unix:/run/php/php7.0-fpm.sock to unix:/var/run/php/php7.0-fpm.sock in Nginx Conf and Sites-available files for the testing purpose. I’ll update soon if the error appears again.

Here’s a summary of what fixed this error: In /etc/php/7.0/fpm/pool.d/www.conf change the lines as below: listen = /var/run/php/php7.0-fpm.sock In /etc/nginx/sites-available/your_site.conf: Under “location ~ .php$ {” change the line to: fastcgi_pass unix:/var/run/php/php7.0-fpm.sock; Restart nginx: sudo service nginx restart Everything should then work.
