I have been working on this for most of the day but it is apparent I am totally out of my depth.
I upgraded my Vultr server with some extra RAM. Once everything come back on line I was getting a 502 gateway error
The nginx logs have the following error
[error] 18221#0: *1 connect() to unix:/var/php-nginx/15140377756735.sock/socket failed (111: Connection refused) while connecting to upstream, client: 220.127.116.11, server: domain.com.au, request: "GET /favicon.ico HTTP/1.1", upstream: "fastcgi://unix:/var/php-nginx/15140377756735.sock/socket:"
I have researched and tried things but getting nowhere.
Appreciate any help someone more experienced could offer.
