Smooth GPS data
...w location estimates. A higher Q parameter means that the accuracy decays faster. Kalman filters generally work better when the accuracy decays a bit quicker than one might expect, so for walking around with an Android phone I find that Q=3 metres per second works fine, even though I generally wal...

...or the user software aborts the connection. So check if uWSGI is answering fast or not of if there is any load on uWSGI / Database server.
In many cases there are some other proxies between the user and nginx. Some can be in your infrastructure like maybe a CDN, Load Balacer, a Varnish cache etc. O...
