Error when teleporting and spoofing not working

[Pedrolyse]

Hello, thanks for the amazing work on the app hovewer I haven't been able to get it to work. My phone is detected and provisionned correctly, hovewer when i load a GPX from the included list, the dot correcty moves along the path in the app however in my pogo app i am still at my usual location, not moving. Also when i tried the teleport function i got this error after double clicking a spot on the map:

Line 122: using (HttpWebResponse response = request.GetResponse() as HttpWebResponse) Error: System.Net.WebException. Distant server returned an error : (400) Incorrect request.

To note I am using the 4G on my phone to act as router for internet access on the computer. Could that mess up with the app somehow?

Thank you for your help.
