Every 2-4 weeks I get (111: Connection refused) while connecting to upstream. Why?
I have a rails app that uses Nginx and Puma. Every 2-4 weeks my app starts giving 502 errors. When digging into log files, this is the error that comes up
[error] 8353#8353: *38966 connect() to unix:///home/deploy/apps/later_backend/shared/tmp/sockets/later_backend-puma.sock failed (111: Connection refused) while connecting to upstream, client: 184.108.40.206, server: later.bz, request: "GET / HTTP/1.1", upstream: "http://unix:///home/deploy/apps/later_backend/shared/tmp/sockets/later_backend-puma.sock:/", host: "later.bz", referrer: "http://later.bz"
A restart will fix the issue but I’m getting really sick of my app crashing every 2-4 weeks and having to do a manual restart. Amy thoughts on what this could be?
