Suddenly I received a 502 Bad gateway notification. Tried updating PHP5-FPM, update nginx, updated ee but still have the issue
@edmund
It seems like your php process is not running,
please use following command to restart php:
sudo service php5-fpm restart
Thanks, forgot to mention I got it solved before that.
Glad to know your issue got solved. I am closing this support thread. If you face any other issue in future, please create another thread.
