Yesterday I was messing around with Pinterest to see how they do their Facebook integration. I set up a test account and went about my way. This morning, I started getting emails from them, so I clicked on “Change your email preferences” with the intention of unsubscribing.
What greeted me was the 502 error you see to your right. 502 is the HTTP error code for “Bad Gateway”. This implies that some sort of networking error is preventing me from reaching their site. But that’s not the case. Having seen similar failure scenarios years ago when I coded Status Shuffle, I had a pretty good guess of what the problem was.
Let me give you a hint: I switched to my other browser, loaded the same link, and it worked like a charm.
