[Interest] Regarding Map Route navigation

[Blasche Alexander]

Hi,


I ran you snippet as is. My only change was to remove the proxy line. The app works and map, route and circle behave as expected. Since this is a network error maybe the proxy is related to the error but I have no proxy to test this with. Did you try without a proxy?


I used Qt 5.4 to test this.
