Why do I have to wait before downloading VK audio on Android?

Question

Android

A long pause was noticed when trying to play audio in the office. VK application for Android.
More accessible: I turn on the track, wait five minutes, only after that it starts to load the track. Loads at normal speed.
Characteristics: Alcatel pop C5, Android 4.2.2, of. client latest version.
Notes: When playing through all browsers (standard, chrome, dolphin), it behaves the same, and sometimes does not load at all.

Answer 1

It seems that the connection setup is not smooth and takes more time than the download of the track. There can be many reasons for this behavior, but I would start by installing a sniffer and reviewing its logs. If the problem is in establishing a connection, you will see this in the server's responses.
After that, you can already draw conclusions and move on.
