Question
PHP + Laravel + Nginx getting "111: Connection refused" error

Asked by Henok
One of my DO servers that we are using as a test environment works well most of the time, but at seemingly random times, the server responds with a “502 Bad Gateway” error.
In the nginx logs, I can see the following error message: 2019/06/27 13:46:15 [error] 1013#1013: *19539 connect() to unix:/var/run/php/php7.3-fpm.sock failed (111: Connection refused) while connecting to upstream, client: 117.204.xxx.xxx, server: subdomain1.sometestdomain123.xyz, request: “POST /client/communicationNotifyAlerts HTTP/2.0”, upstream: “fastcgi://unix:/var/run/php/php7.3-fpm.sock:”, host: “subdomain1.sometestdomain123.xyz”, referrer: “https://subdomain1.sometestdomain123.xyz/client/api1”
I’m guessing this could be happening after updating our php code but not performing a restart? Could this be caused by something else.

Hello,
It looks like that your PHP FPM service is crashing. If you see that 502 error just try starting PHP FPM and it should start working as normal.
I would recommend checking your syslogs to further investigate the problem, maybe your server is out of RAM and that’s why PHP FPM gets killed.
