So all I know is that unicorn is not communicating with nginx. No idea why. This was working fine up until this most recent git pull.
Things I have tried that have not fixed the issue:
service unicorn restart
service nginx reload
restarting my server
gem install bundle
manually removing the Gemfile.lock file and running bundle install again
in unicorn.conf, Changing the line
manually removing the unicorn.sock file and verifying it is regenerated with a unicorn restart.
What further can I do to troubleshoot this problem? Why did this happen? How can I fix it?
