I've recently started getting the following error when attempting to access the admin interface on my Rails 3 Jumpbox:
"503 Internal Server Error: Bad Gateway"
I'm using Rails 3.0.8 with RVM and have updated the Jumpbox from ree1.8.7 to Ruby 1.9.2p180. Everything seems to be working fine, except the admin interface.
I did some previous searching on the forums and saw the instructions for restarting mongrel, but I don't know whether those are applicable to the Rails 3 Jumpbox. I didn't think Mongrel was compatible with Rails 3, and the command to start Mongrel results in a "no such file to load -- mongrel_rails" error.
Any help would be appreciated!
