Preemptive HTTP authentication for Ivy repositories

Is version 2.7’s preemptive HTTP authentication also support to work with Ivy repositories? Because I’m trying to access a private GitHub repository that is hosting an Ivy repository with a custom layout, and I cannot get it to run. The URL as displayed as part of “Searched in the following locations” is correct, my credentials are correct, and I’ve added “basic(BasicAuthentication)”. Yet it doe snto work and I get “Could not resolve all dependencies”.
