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

Getting 502 Bad Gateway error while opening websites link.
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!
