Game Instance Subsystem doesn't work

I created the UGameInstanceSubsystem parent class from Unreal Engine for some http requests.
Then i try to make some requests from widget and discovered that GetSubsystem() func returns nullptr.

In my UHttpServicesSubsystem class Initialize() doesn’t work too.

Could someone help me to understand what i did wrong?

This log is not displayed at all

The problem was that I override the Init() function in GameInstance and forgot to add Super::Init() to it)
Pain and fun))
