And yes - server's reply is not received mostly, if this crash. But sometimes works OK as before, reply is received from server and no crash.
How to debug ?

Are you using OkHtyputils2

 

[peacemaker]

Yes. Seems, trouble is solved, if do not make HTTP-request just after app start. But situation is still unclear why no clear error log, always reproducing.

 

[Erel]

Can you upload a small project that reproduces this error?
