'768 worker_connections are not enough' Error

Update, I have increased my worker connections for the time being, but I still get these errors (less frequently & for the higher number of workers). I’m really curious if anything changed recently that might cause this, or how I could track this down better.

## Any custom commands to run after building
run:
  - exec: echo "Beginning of custom commands"

  - replace:
      filename: "/etc/nginx/letsencrypt.conf"
      from: "worker_connections 768" 
      to: "worker_connections 1768"
