 * Hi,
 * What exactly do you mean with ‘login with trackme’?
 * Where is this error shown? Inside TrackMe?
 * I haven’t tested TrackeMe on Windows Phone at all, so I’m not sure if it works.
   Trackserver is only tested with TrackMe on Android.

    Martijn.

 * Hi,
 * I think Trackserver is not compatible with TrackMe on Windows Phone. Apparently,
   Trackserver sends a response that TrackMe does not understand, while authenticating
   the user. It is strange that the first entry is recorded but subsquent request
   are failing. I cannot explain that.
 * Unfortunately, I do not own a Windows Phone, so there is no way for me to reproduce
   and fix this.
 * The TrackMe protocol is not documented anywhere and I reverse-engineered it from
   the web viewer ([https://github.com/espinosaluis/TrackMeViewer](https://github.com/espinosaluis/TrackMeViewer)).
   If you can confirm that the phone app works with that web viewer, it should also
   be possible to make it work with Trackserver. However, I think TrackMe for Windows
   phone hasn’t been updated since 2011, so I’m not sure if it worth the effort.
 * Best regards,
    Martijn.

 * I am closing this issue due to lack of more information. There isn’t much I can
   do regarding support for TrackMe on Windows. I would accept a pull request on
   Github though. Trackserver’s source is hosted here:
