Instagram location endpoind media/recent always return empty array
It works for now. However, the response depends on your token. Some tokens seems like valid but return you empty responses.
After I faced this problem I started using http://services.chrisriversdesign.com/instagram-token/ service to generate instagram tokens which work correctly with instagram media API requests.
I'm experiencing the same thing right now.
Here's what most likely caused the OP issue:
Judging by the date and time of your post, it was an issue with the Facebook and Instagram servers being down for about 90 mins.
According to a Jan 26 post on Facebook's developer page:"Facebook and Instagram experienced a major outage tonight from 22:10 until 23:10 PST. Our engineers identified the cause of the outage and recovered the site quickly. You should now see decreasing error rates while our systems stabilize. We don't expect any other break in service. I'll post another update within 30 mins. Thank you for your patience."
