Keywords: WordPress + NGINX + SSL - Microsoft Azure - Technical issue - Secure Connections (SSL/HTTPS)
We are using a Bitnami WordPress with NGINX and SSL 4.9.8-0 on a azure VM. we were getting 502 error for all the requests. when we checked the nginx logs we got the following error:
2018/12/05 04:27:37 [error] 2672#0: *17167 connect() to unix:/opt/bitnami/php/var/run/www.sock failed (11: Resource temporarily unavailable) while connecting to upstream, client: 126.96.36.199, server: localhost, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/opt/bitnami/php/var/run/www.sock:", host: "www.example.com"
we restarted the services using the ctrl script and the website is working now.
is there any connection limitations in the default settings which we have to change. please help us to solve the issue permanently.
