We have a live iOS/Android app that has been having issues since we had a DYN/DNS problem. We recently switch DNS servers, which fixed all of those issues, but we are still getting 502 Gateway Bad errors on a critical ubuntu server running nginx. We no longer have a back-end developer on staff, and need immediate help on getting a critical piece of our back-end up and running.
We did in fact hire a Freelancer from this site for one of our servers. However, when our discovery made us realize we had issues on the other one, the freelancer did not have the Ruby experience required for that job. So, if you have seen this post before, this is an update to our issue.
