http credentials not working

[baurzhan]

I am using Gitlab CI to build binary artifacts from my source files. I have a class library project Example. In other project I added http dependency to my library class binary.
I configured credentials:
paket config add-credentials "https://example.com"
And in paket.dependencies file:
https://example.com/group/example/builds/artifacts/master/file/release-net/example.dll?job=package net/example/example.dll

But this downloads login page.
