I'm attempting to start my rails server, but I'm getting the error trace below.
I've commented out the line mentioned here:
4.2.0/lib/audited/auditor.rb:48:in `audited'
from /home/david-vm/Documents/rails_projects/bane/app/models/user.rb:9:in `<class:User>'
, and I can get it to run, but I'm not sure why that is breaking it. So I was thinking of maybe using byebug to trace down the issue, but can't seem to figure out how I would go about that. Or is there another way I can troubleshoot this issue? Thanks!

Update
Turns out it was a DNS issue, so even though my database.yml hadn't changed- the server name was no longer working. Just added the update in case anyone is having this similar issue, might be worth checking this out.
The answer is IN the stack trace. It's telling you exactly what file ON your system is having the error. The fact that that file came from a gem, or lives in a different part of your computer, is irrelevant.
/home/david-vm/.rvm/gems/ruby-2.3.0/gems/tiny_tds-0.7.0/lib/tiny_tds/client.rb:74:in `connect': Server name not found in configuration files (TinyTds::Error)
Open that file (or whatever file in the backtrace seems most appropriate) with your editor, stick a binding.pry (or byebug, or debugger, whatever you're using) in there before the line it's blowing up on (74). Then restart your app and debug as if it was a file in your app.
