Self hosted - can not search users

Brothers and Sisters. I have installed jams server, testing with native jami client for linux. I can login to created account, but can not search other accounts with some kind of authentication issue.
How can i trace this issue deeper ? Can. not find any helpful information on server level.
Connection is plain http - dont use SSL (i think its not related).
