I installed discourse by following instructions on: http://blog.discourse.org/2014/04/install-discourse-in-under-30-minutes/
It ran absolutely fine for a few months and during this time I also updated the installation a couple of times.
A couple of weeks ago I tried to update it again, but there was some error in the middle of the update but still the site was working fine (to my knowledge).
However, then suddenly the site started giving “502 bad gateway” error. It is running on 1GB VPS on linode.
I have no experience with nginx and rails. Can you please let me know how can I fix this?
The site is: http://www.attractdreamlife.com/
Thanks in advance. (I am willing to share root details of the server in private with an expert who can help me out.)
