Invalid Location

[guotao]

Thanks for good work, Because API not work for some day, I set up the API-layer, on my server, but meet some problem,

The profile: https://github.com/iffe-team/speedtracker/blob/master/_profiles/default.html

works fine before, but in my server , it response:

error: { code: "WPT_ERROR", message: "Invalid Location, please try submitting your test request again." },

I think the location's format is not correct, but cant find too much info ,can you help me fix it ?
