Standalone OBS instance gives "unresolvable: nothing provides" for dependant packages

I’ve got a problem on my own hosted OBS (v2.8) instance. Dependant packages can not be built.
Made test project with package1 and package2. **package2 **depends on **package1
**Same setup on public OBS here works like a charm.

So! Where should I dig in to get what`s wrong?
