I had a Rails app running on my computer locally(localhost:3000). I just updated from rails 5.0 to 5.1 and now when I run rails s I'm getting a 502 Bad Gateway nginx/1.14.0.
=> Booting Passenger application server
=> Rails 5.1.7 application starting in production on http://0.0.0.0:3000
=> Run `rails server -h` for more startup options
=============== Phusion Passenger Standalone web server started ===============
PID file: /mnt/c/Users/Username/Desktop/Projects/2. Web Applications/WebSite/tmp/pids/passenger.3000.pid
Log file: /mnt/c/Users/Username/Desktop/Projects/2. Web Applications/WebSite/log/passenger.3000.log
Environment: production
Accessible via: http://0.0.0.0:3000/
I don't ever remember having to set up Nginx to run a rails app on my computer locally before. I also recall it usually started on http://localhost:3000 or http://127.0.0.1:3000.

Any suggestions would be super helpful. If more information is needed let me know.
Thanks.
UPDATE:
Restarting my machine got rid of the 502 error (guess "turning it off and on again" did work, thanks IT gods).
However, now I'm getting another error:
